2-(3-Chloro-4-(methylthio)phenyl)acetic acid CAS 87776-75-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Chloro-4-(methylthio)phenyl)acetic acid.

2-(3-Chloro-4-(methylthio)phenyl)acetic acid (CAS 87776-75-8), molecular formula C9H9ClO2S and molecular weight 216.68 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(3-Chloro-4-(methylthio)phenyl)acetic acid (C9H9ClO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-(3-Chloro-4-(methylthio)phenyl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
