Argatroban Impurity 55 CAS CATO-C4X-100755

Description

Compared with other compounds in its class, the molecular weight of 577.65 g/mol gives Argatroban Impurity 55 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Argatroban Impurity 55 (CAS CATO-C4X-100755) is a certified pharmaceutical impurity reference standard with the molecular formula C25H35N7O7S and a molecular weight of 577.65 g/mol.

The molecular framework of Argatroban Impurity 55 (C25H35N7O7S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

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.

CATO manufactures Argatroban Impurity 55 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.
