Ceftriaxone Impurity 41 CAS 473843-58-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ceftriaxone Impurity 41.

CATO supplies Ceftriaxone Impurity 41 (CAS 473843-58-2), a pharmacopoeial impurity reference standard (molecular formula C18H22N6O8S2, MW 514.53 g/mol) used for the identification and quantification of trace impurities in APIs.

Ceftriaxone Impurity 41 (C18H22N6O8S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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), Ceftriaxone Impurity 41 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.
