Argatroban Impurity 3 CAS 20668-20-6 chemical structure

Description

As a certified reference material (CRM), Argatroban Impurity 3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Argatroban Impurity 3 (CAS 20668-20-6), a pharmacopoeial impurity reference standard (molecular formula C10H13N, MW 147.22 g/mol) used for the identification and quantification of trace impurities in APIs.

Argatroban Impurity 3 (C10H13N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
