Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 595.71 g/mol gives Vecuronium Bromide EP Impurity E distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Vecuronium Bromide EP Impurity E (CAS 50587-95-6) is a certified pharmaceutical impurity reference standard with the molecular formula C32H55N2O3Br and a molecular weight of 595.71 g/mol.
The molecular framework of Vecuronium Bromide EP Impurity E (C32H55N2O3Br) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
CATO manufactures Vecuronium Bromide EP Impurity E 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.
