CATO manufactures Pinaverium Bromide Impurity 5 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 Pinaverium Bromide Impurity 5 (CAS 135964-95-3), a pharmacopoeial impurity reference standard (molecular formula C26H41BrNO4Br, MW 591.42 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Pinaverium Bromide Impurity 5 (C26H41BrNO4Br) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
