Everolimus Impurity 38 CAS CATO-C4X-112238 chemical structure

Description

CATO manufactures Everolimus Impurity 38 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Everolimus Impurity 38 (CAS CATO-C4X-112238), a pharmacopoeial impurity reference standard (molecular formula C54H85NO15, MW 988.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Everolimus Impurity 38 (C54H85NO15) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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).

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.
