Description
CATO supplies Fluconazole Impurity 51 (CAS CATO-C4X-101951), a pharmacopoeial impurity reference standard (molecular formula C36H29F6N15O2, MW 817.71 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Fluconazole Impurity 51 (C36H29F6N15O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 27.0, corresponding to approximately 27 ring(s) or double-bond equivalent(s). With a molecular weight of 817.71 g/mol, it falls into the 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 Fluconazole Impurity 51 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.
