Empagliflozin Impurity 116 CAS 19311-38-7

Description

Compared with other compounds in its class, the molecular weight of 106.55 g/mol gives Empagliflozin Impurity 116 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Empagliflozin Impurity 116 (CAS 19311-38-7), a pharmacopoeial impurity reference standard (molecular formula C4H7ClO, MW 106.55 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Empagliflozin Impurity 116 (C4H7ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 106.55 g/mol, it falls into the low-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 116 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.
