Chemical Structure
Description
CATO supplies 2-(3-Hydroxy-5-methoxyphenyl)acetic acid (CAS 367259-05-0), a certified reference material (molecular formula C9H10O4, MW 182.17 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Hydroxy-5-methoxyphenyl)acetic acid (C9H10O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-(3-Hydroxy-5-methoxyphenyl)acetic 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.
