Chemical Structure

Everolimus Impurity 32 CAS CATO-C4X-112232 chemical structure

Description

CATO supplies Everolimus Impurity 32 (CAS CATO-C4X-112232), a pharmacopoeial impurity reference standard (molecular formula C55H89NO14, MW 988.29 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Everolimus Impurity 32 (C55H89NO14) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Everolimus Impurity 32 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.
