2-Ethyl-5-hydroxybenzoic acid CAS 52008-91-0

Description

Compared with other compounds in its class, the molecular weight of 166.17 g/mol gives 2-Ethyl-5-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Ethyl-5-hydroxybenzoic acid (CAS 52008-91-0), a certified reference material (molecular formula C9H10O3, MW 166.17 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Ethyl-5-hydroxybenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-Ethyl-5-hydroxybenzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
