2-Methoxy-4-mercaptobenzoic Acid CAS 95420-72-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methoxy-4-mercaptobenzoic Acid.

2-Methoxy-4-mercaptobenzoic Acid (CAS 95420-72-7), molecular formula C8H8O3S and molecular weight 184.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Methoxy-4-mercaptobenzoic Acid (C8H8O3S) 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 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-Methoxy-4-mercaptobenzoic 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.
