Thioctic acid Impurity 96 CAS CATO-C4X-152696

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 96 (CAS CATO-C4X-152696), a pharmacopoeial impurity reference standard (molecular formula C24H44O6S6, MW 620.99 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C24H44O6S6, Thioctic acid Impurity 96 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 620.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), Thioctic acid Impurity 96 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.
