Chemical Structure

Dabigatran Impurity 22 CAS 1408238-41-4 chemical structure

Description

The occurrence of Dabigatran Impurity 22 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Dabigatran Impurity 22 (CAS 1408238-41-4), a pharmacopoeial impurity reference standard (molecular formula C19H21N5O2, MW 351.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Dabigatran Impurity 22 (C19H21N5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 351.40 g/mol, it falls into the moderately-high-molecular-weight range. 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), Dabigatran Impurity 22 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.
