Dasatinib Impurity 77 CAS CATO-C4X-160777

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dasatinib Impurity 77.

CATO supplies Dasatinib Impurity 77 (CAS CATO-C4X-160777), a pharmacopoeial impurity reference standard (molecular formula C21H16Cl3N7OS, MW 520.82 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C21H16Cl3N7OS, Dasatinib Impurity 77 contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 520.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Dasatinib Impurity 77 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.
