Chemical Structure

Empagliflozin impurity 182 CAS 915095-83-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 381.65 g/mol gives Empagliflozin impurity 182 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Empagliflozin impurity 182 (CAS 915095-83-9), a pharmacopoeial impurity reference standard (molecular formula C17H14BrClO3, MW 381.65 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Empagliflozin impurity 182 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.65 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.

CATO manufactures Empagliflozin impurity 182 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
