Clofarabine Impurity 13 CAS 1904-98-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Clofarabine Impurity 13.

CATO supplies Clofarabine Impurity 13 (CAS 1904-98-9), a pharmacopoeial impurity reference standard (molecular formula C5H6N6H2O, MW 168.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Clofarabine Impurity 13 (C5H6N6H2O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Clofarabine Impurity 13 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.
