Dapagliflozin Impurity 114 CAS CATO-C4X-1138114

Description

Compared with other compounds in its class, the molecular weight of 727.62 g/mol gives Dapagliflozin Impurity 114 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Dapagliflozin Impurity 114 (CAS CATO-C4X-1138114), a pharmacopoeial impurity reference standard (molecular formula C34H59ClO7Si4, MW 727.62 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Dapagliflozin Impurity 114 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 727.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
