Chemical Structure

Thioctic acid Impurity 26 CAS 2114407-76-8 chemical structure

Description

CATO manufactures Thioctic acid Impurity 26 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.

As a process- or degradation-related impurity, Thioctic acid Impurity 26 (CAS 2114407-76-8, C8H14O3S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Thioctic acid Impurity 26 (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.
