Compared with other compounds in its class, the molecular weight of 339.61 g/mol gives Dapagliflozin Impurity N51 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dapagliflozin Impurity N51 (CAS 1404477-10-6) is a certified pharmaceutical impurity reference standard with the molecular formula C15H12BrClO2 and a molecular weight of 339.61 g/mol.
Based on its molecular formula C15H12BrClO2, Dapagliflozin Impurity N51 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Dapagliflozin Impurity N51 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.
