2-(2-Chloro-5-hydroxyphenyl)acetic acid CAS 149029-87-8

Description

Compared with other compounds in its class, the molecular weight of 186.59 g/mol gives 2-(2-Chloro-5-hydroxyphenyl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(2-Chloro-5-hydroxyphenyl)acetic acid (CAS 149029-87-8), a certified reference material (molecular formula C8H7ClO3, MW 186.59 g/mol) for analytical method development and quality control.

2-(2-Chloro-5-hydroxyphenyl)acetic acid (C8H7ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-(2-Chloro-5-hydroxyphenyl)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.
