Argatroban Impurity 31 CAS 632-22-4 chemical structure

Description

CATO manufactures Argatroban Impurity 31 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 Argatroban Impurity 31 (CAS 632-22-4), a pharmacopoeial impurity reference standard (molecular formula C5H12N2O, MW 116.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C5H12N2O, Argatroban Impurity 31 contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 116.16 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.

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.
