Chemical Structure

Thioctic acid Impurity 68 CAS CATO-C4X-152668 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 222.32 g/mol gives Thioctic acid Impurity 68 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Thioctic acid Impurity 68 (CAS CATO-C4X-152668, C8H14O3S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Thioctic acid Impurity 68 (C8H14O3S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 222.32 g/mol, it falls into the medium-molecular-weight range.

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 68 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.
