Description
CATO manufactures Buserelin EP Impurity D 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 Buserelin EP Impurity D (CAS CATO-C4X-22124), a pharmacopoeial impurity reference standard (molecular formula C60H86N16O13C2H4O2, MW 1299.50 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Buserelin EP Impurity D (C60H86N16O13C2H4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 26.0, corresponding to approximately 26 ring(s) or double-bond equivalent(s). With a molecular weight of 1299.50 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.
