As a certified reference material (CRM), Bacampicillin EP Impurity I N,N'-Dibenzylethylenediamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Bacampicillin EP Impurity I N,N'-Dibenzylethylenediamine (CAS 33276-75-4) is a certified pharmaceutical impurity reference standard with the molecular formula C17H20N2O4SC16H20N2 and a molecular weight of 588.77 g/mol.
The molecular framework of Bacampicillin EP Impurity I N,N'-Dibenzylethylenediamine (C17H20N2O4SC16H20N2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
