Product overview

What is Magnesium Malate?

Magnesium Malate is an organic magnesium salt identified as magnesium 2-hydroxybutanedioate and malic acid magnesium salt (1:1). Its CAS number is 869-06-7, molecular formula is C4H4MgO5, and stated molecular weight is 156.38. The compound contains magnesium associated with the hydroxybutanedioate anion, providing a distinct salt form within the broader family of organic magnesium compounds used in commercial and technical chemistry.

As a salt, Magnesium Malate is expected to participate in ionic and acid-base behaviour characteristic of magnesium carboxylates, while the hydroxycarboxylate component contributes organic-acid functionality. Its practical behaviour can depend on particle characteristics, moisture exposure, formulation conditions, concentration, temperature and the specifications of a particular material. Solubility, handling and compatibility should therefore be established for the intended process rather than assumed from identity alone.

Magnesium malate is encountered in professional formulation, laboratory and chemical-processing contexts where a magnesium salt associated with malate is desired. Potential relevance includes research, composition development and selected manufacturing work involving organic magnesium compounds. A common use category or market description does not establish suitability for food, pharmaceutical, personal-care or other regulated applications; those decisions require assessment of the applicable grade, process and jurisdiction.

Selection should begin with the required composition, documented quality attributes and intended route of use. Users should consider water content, particle form, dissolution behaviour, impurity controls, analytical method compatibility and interaction with other ingredients or process materials. Storage and handling conditions should protect the material from unsuitable moisture, contamination and environmental exposure. Final acceptance remains the responsibility of the purchaser's qualified technical and regulatory teams.

Detailed product information

Detailed Magnesium Malate product information

Composition and Chemical Identity

Magnesium Malate is the 1:1 magnesium salt of malic acid, represented by the formula C4H4MgO5. The defined identity supports work requiring a named organic magnesium compound rather than an unspecified magnesium source. Its malate component contains both hydroxyl and carboxylate functionality, which can influence ionic interactions, acidity and formulation behaviour. Identity alone does not define a particular commercial grade or end-use approval.

The stated molecular weight is 156.38, and the material is also described by the systematic name magnesium 2-hydroxybutanedioate. These identifiers help distinguish it from magnesium citrate, magnesium glycinate, magnesium oxide and other magnesium compounds. When comparing materials, users should review the complete specification and analytical basis, because naming conventions, hydration state, residual components and manufacturing controls can affect practical equivalence.

Properties and Formulation Behaviour

Magnesium Malate combines a divalent magnesium centre with an organic hydroxycarboxylate ligand. In solution or a suitably polar formulation environment, the salt may contribute magnesium ions and malate-related species, with the balance influenced by concentration, pH, temperature and surrounding ingredients. The degree and rate of dissolution should be measured under actual process conditions, especially when developing concentrated blends, suspensions or solid-dose systems.

Compatibility assessment is important when Magnesium Malate is combined with acids, bases, chelating agents, phosphates, carbonates or other mineral salts. Such components may alter ionic balance, precipitation tendency or apparent solubility. Moisture, milling, blending energy and storage conditions can also affect flow and uniformity. Technical trials should use representative material and define acceptance criteria before scale-up or routine production.

Professional Uses and Market Context

Magnesium Malate may be considered in research and development involving organic magnesium salts, comparative formulation studies and selected chemical manufacturing processes. It can also serve as a reference material for analytical work where the target composition is magnesium associated with malate. These contexts describe potential technical relevance, not a universal claim that every material is suitable for a regulated product or a particular route of administration.

Interest in magnesium malate may arise where formulators are comparing organic magnesium salts by composition, handling profile, dissolution behaviour or compatibility with a wider system. Comparisons with other magnesium salts should use equivalent test conditions and clearly defined endpoints. A similar marketing name does not guarantee equivalent elemental magnesium content, impurity profile, physical form or processing performance.

Selection, Handling and Quality Review

For Magnesium Malate, a responsible selection process should match the material's documented identity and quality attributes with the intended application. Review the assay basis, elemental composition, moisture, residual solvents where relevant, particle characteristics, microbiological controls where applicable and test methods appropriate to the finished formulation. Requirements may differ substantially between laboratory research, industrial blending and regulated manufacturing, so a single generic specification should not be assumed.

During handling, keep containers closed when practical and use clean, dry equipment appropriate to the material and process. Prevent cross-contamination and evaluate dust-control measures for powder operations. Store under conditions established by the responsible quality team, taking account of humidity, temperature and light sensitivity if relevant to the formulation. Before use, confirm that the selected material meets the purchaser's internal, legal and customer requirements.

Frequently asked questions

Questions about Magnesium Malate

Why does material specification matter when evaluating Magnesium Malate?

Chemical identity confirms that the material is Magnesium Malate, but it does not by itself define purity, physical form, concentration, test methods or suitability for a particular process. Those details belong to the current supplier specification and related documentation. Technical and purchasing teams should compare that information with the intended formulation, operating conditions and internal approval criteria before use. If the supplier, grade, process or end-use requirement changes, the earlier assessment may no longer apply. Keeping identity and specification separate helps prevent similarly named or differently supplied materials from being treated as automatically interchangeable. It also creates a clearer record for receiving, quality review and later change control.

How can Magnesium Malate behave in water-based formulations?

Behaviour in a water-based system depends on concentration, temperature, pH, agitation, particle characteristics and the presence of other dissolved materials. Magnesium Malate may dissociate to a degree, producing magnesium-containing and malate-related species, but the observed dissolution rate or clarity can vary with formulation conditions. Other salts, acids, bases, phosphates, carbonates and chelating ingredients may change ionic equilibria or create precipitation risks. A small bench test under representative conditions is more informative than relying only on the chemical name. Development teams should record mixing order, equilibration time, temperature and concentration, then confirm the result with an appropriate analytical or physical test.

How does Magnesium Malate differ from other magnesium salts?

The principal distinction is the accompanying anion. Magnesium Malate contains malate, an organic hydroxycarboxylate derived from malic acid, whereas magnesium citrate contains citrate, magnesium glycinate contains a glycine-related ligand, and magnesium oxide is an inorganic oxide. These differences affect formula mass, elemental magnesium proportion, acid-base behaviour, dissolution characteristics, taste considerations and compatibility. Comparisons should not rely on a simple product name or a perceived benefit. Use equivalent concentration bases and measure the property that matters for the intended application, such as elemental magnesium content, dissolution time, solution appearance, stability or process recovery. Grade-specific data remain essential for a meaningful comparison.

What formulation factors should be assessed before using Magnesium Malate?

Assessment should cover the target concentration, solvent or carrier, pH, temperature, mixing sequence and contact time. Teams should also examine interactions with mineral salts, organic acids, bases, chelators, binders, sweeteners, polymers or other excipients used in the final system. Powder flow, segregation, moisture uptake and dissolution can influence manufacturing consistency even when the chemical identity is acceptable. A compatibility study should include appearance, assay or identification, water content where relevant and any product-specific stability indicators. The appropriate test plan depends on the application and jurisdiction. Do not infer finished-product suitability solely from a general description of Magnesium Malate.

Can Magnesium Malate be used in regulated food, supplement or pharmaceutical products?

Potential use in a regulated product depends on the applicable jurisdiction, product category, intended purpose, manufacturing controls and the specific material specification. A chemical identity and common market terminology do not establish legal acceptance, permitted use level, monograph status, purity, contaminant limits or suitability for human consumption. Regulatory and quality teams should review current local requirements, supplier documentation, analytical results and the finished-product process. They should also confirm whether the selected material meets any applicable food, supplement, pharmaceutical or personal-care standards. This catalogue description is technical information for professional evaluation, not a regulatory determination or a medical, nutritional or therapeutic claim.

How should Magnesium Malate be handled during development and manufacturing?

Handle the material using procedures appropriate for a powdered organic magnesium salt and the site's risk assessment. Keep equipment clean, minimise contamination and consider local dust-control measures during charging, transfer, sieving or blending. Protect the material from unsuitable humidity and environmental exposure, and use closed containers or equivalent controls when practical. Personnel should consult the current safety documentation, workplace procedures and applicable regulations before handling. Process teams should verify that storage conditions preserve the required quality attributes and that weighing and dispensing controls prevent mix-ups. Any unusual odour, appearance, caking or processing behaviour should trigger evaluation under the site's quality system before further use.
