Chemical Structure

Thioctic acid impurity 64 CAS CATO-C4X-152664 chemical structure

Description

As a certified reference material (CRM), Thioctic acid impurity 64 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.

As a process- or degradation-related impurity, Thioctic acid impurity 64 (CAS CATO-C4X-152664, C8H14O3S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Thioctic acid impurity 64 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
