Thioctic acid Impurity 88 Sodium Salt (Mixture of Isomers) CAS CATO-C4X-152688

Description

Compared with other compounds in its class, the molecular weight of 244.30 g/mol gives Thioctic acid Impurity 88 Sodium Salt (Mixture of Isomers) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Thioctic acid Impurity 88 Sodium Salt (Mixture of Isomers) (CAS CATO-C4X-152688, C8H13O3S2Na) 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 88 Sodium Salt (Mixture of Isomers) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
