Chemical Structure

Thioctic acid Impurity 36 CAS 2635383-46-7 chemical structure

Description

As a process- or degradation-related impurity, Thioctic acid Impurity 36 (CAS 2635383-46-7, C10H18O2S3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Thioctic acid Impurity 36 (C10H18O2S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 manufactures Thioctic acid Impurity 36 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.
