Thioctic Acid Impurity 46 CAS 940-69-2 chemical structure

Description

CATO manufactures Thioctic Acid Impurity 46 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 46 (CAS 940-69-2) is a certified pharmaceutical impurity reference standard with the molecular formula C8H15NOS2 and a molecular weight of 205.34 g/mol.

Based on its molecular formula C8H15NOS2, Thioctic Acid Impurity 46 contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 205.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
