Chemical Structure

Fovinaciclib Impurity 5 CAS CATO-C4X-33865 chemical structure

Description

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 supplies Fovinaciclib Impurity 5 (CAS CATO-C4X-33865), a pharmacopoeial impurity reference standard (molecular formula C28H38N8OSHCl, MW 571.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Fovinaciclib Impurity 5 (C28H38N8OSHCl) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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).

As a certified reference material (CRM), Fovinaciclib Impurity 5 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.
