Description
CATO supplies Capivasertib Impurity 36 (CAS CATO-C4X-331236), a pharmacopoeial impurity reference standard (molecular formula C20H33IO4, MW 464.38 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Capivasertib Impurity 36 (C20H33IO4) contains a steroid core, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 464.38 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Capivasertib Impurity 36 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.
