Chemical Structure

Empagliflozin Impurity 43 CAS CATO-C4X-106543 chemical structure

Description

The occurrence of Empagliflozin Impurity 43 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Empagliflozin Impurity 43 (CAS CATO-C4X-106543), a pharmacopoeial impurity reference standard (molecular formula C13H11ClIN, MW 343.59 g/mol) used for the identification and quantification of trace impurities in APIs.

Empagliflozin Impurity 43 (C13H11ClIN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Empagliflozin Impurity 43 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.
