Chemical Structure

Thioctic acid Impurity 27 CAS 2114407-82-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Thioctic acid Impurity 27.

CATO supplies Thioctic acid Impurity 27 (CAS 2114407-82-6), a pharmacopoeial impurity reference standard (molecular formula C8H14O3S2, MW 222.32 g/mol) used for the identification and quantification of trace impurities in APIs.

Thioctic acid Impurity 27 (C8H14O3S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

As a certified reference material (CRM), Thioctic acid Impurity 27 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.
