Thioctic Acid Impurity 52 CAS CATO-C4X-152652 chemical structure

Description

As a certified reference material (CRM), Thioctic Acid Impurity 52 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 Thioctic Acid Impurity 52 (CAS CATO-C4X-152652), a pharmacopoeial impurity reference standard (molecular formula C8H14O3S, MW 190.26 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Thioctic Acid Impurity 52 (C8H14O3S) 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.

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.
