Chemical Structure

Empagliflozin Impurity 280 CAS 2562349-63-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 478.92 g/mol gives Empagliflozin Impurity 280 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Empagliflozin Impurity 280 (CAS 2562349-63-5) is a certified pharmaceutical impurity reference standard with the molecular formula C24H27ClO8 and a molecular weight of 478.92 g/mol.

Based on its molecular formula C24H27ClO8, Empagliflozin Impurity 280 contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 478.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 280 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.
