Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1450.24 g/mol gives Vancomycin EP Impurity L distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Vancomycin EP Impurity L (CAS 79517-31-0), a pharmacopoeial impurity reference standard (molecular formula C66H74Cl2N8O25, MW 1450.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C66H74Cl2N8O25, Vancomycin EP Impurity L contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1450.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Vancomycin EP Impurity L 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.
