Chemical Structure
Description
As a certified reference material (CRM), 2-(3-Mercaptophenyl)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.
CATO supplies 2-(3-Mercaptophenyl)acetic acid (CAS 63271-86-3), a certified reference material (molecular formula C8H8O2S, MW 168.21 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Mercaptophenyl)acetic acid (C8H8O2S) is characterized by a sulfone group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
