Thioctic acid Impurity 97 CAS CATO-C4X-152697 chemical structure

Description

CATO manufactures Thioctic acid Impurity 97 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.

Thioctic acid Impurity 97 (CAS CATO-C4X-152697) is a certified pharmaceutical impurity reference standard with the molecular formula C24H44O6S6 and a molecular weight of 620.99 g/mol.

The molecular framework of Thioctic acid Impurity 97 (C24H44O6S6) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
