Elobixibat Impurity 31 CAS CATO-C4X-283831

Description

Compared with other compounds in its class, the molecular weight of 476.47 g/mol gives Elobixibat Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Elobixibat Impurity 31 (CAS CATO-C4X-283831), a pharmacopoeial impurity reference standard (molecular formula C24H30BrNO2S, MW 476.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Elobixibat Impurity 31 (C24H30BrNO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 476.47 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Elobixibat Impurity 31 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.
