Thioctic acid Impurity 89 (Mixture of Isomers) CAS CATO-C4X-152689 chemical structure

Description

CATO manufactures Thioctic acid Impurity 89 (Mixture of Isomers) 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 89 (Mixture of Isomers) (CAS CATO-C4X-152689, C8H14O3S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Thioctic acid Impurity 89 (Mixture of Isomers) (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.

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.
