Chemical Structure

Thioctic acid Impurity 2 CAS 108015-78-7 chemical structure

Description

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO supplies Thioctic acid Impurity 2 (CAS 108015-78-7), a pharmacopoeial impurity reference standard (molecular formula C8H14O3S2, MW 222.32 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Thioctic acid Impurity 2 (C8H14O3S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

CATO manufactures Thioctic acid Impurity 2 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.
