Thioctic acid impurity 62 CAS 93892-06-9 chemical structure

Description

CATO manufactures Thioctic acid impurity 62 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.

CATO supplies Thioctic acid impurity 62 (CAS 93892-06-9), a pharmacopoeial impurity reference standard (molecular formula C10H20O3, MW 188.26 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Thioctic acid impurity 62 (C10H20O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
