Apixaban Impurity 111 CAS 104-94-9

Description

Compared with other compounds in its class, the molecular weight of 123.15 g/mol gives Apixaban Impurity 111 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Apixaban Impurity 111 (CAS 104-94-9), a pharmacopoeial impurity reference standard (molecular formula C7H9NO, MW 123.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, Apixaban Impurity 111 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Apixaban Impurity 111 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.
