Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 495.36 g/mol gives Empagliflozin Impurity 76 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Empagliflozin Impurity 76 (CAS CATO-C4X-106576, C23H27BrO7) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Structurally, Empagliflozin Impurity 76 (C23H27BrO7) contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 495.36 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Empagliflozin Impurity 76 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.
