2-Ethylphenol is an aromatic organic compound in the alkylphenol family. Its systematic name is 2-ethylphenol, and it is also known as o-ethylphenol, phlorol, phenol, o-ethyl-, phenol, 2-ethyl-, and 1-ethyl-2-hydroxybenzene. The compound has CAS number 90-00-6, molecular formula C8H10O, and molecular weight 122.16. Its structure combines a phenolic hydroxyl group with an ethyl substituent on a benzene ring.
As a substituted phenol, 2-ethylphenol contains a polar hydroxyl function alongside a non-polar aromatic and ethyl portion. This combination influences intermolecular interactions, acidity relative to ordinary alcohols, and compatibility with different organic environments. Physical behaviour can vary with temperature, purity, and handling conditions, so users should consult current technical and safety documentation for measured properties relevant to their operation.
2-Ethylphenol is encountered primarily as a chemical intermediate, reference material, or research substance in aromatic chemistry. Its functional groups make it relevant to studies of substitution, oxidation, derivatisation, and formulation behaviour. Potential use in synthesis or analytical work does not by itself establish suitability for a particular process, product category, or regulated application; that determination requires technical evaluation by the responsible user.
Selection should begin with identity confirmation, intended reaction or analytical purpose, and compatibility with the surrounding process. Users may also consider impurity profile, water content, colour, storage conditions, and the effect of phenolic functionality on materials or reagents. Because requirements differ across laboratories and manufacturing systems, a particular commercial grade should be assessed against the receiving specification before technical adoption. For commercial selection, the compound name should be considered separately from the specification and supplied form required for the intended process.
