Pitolisant Impurity 50 CAS 90562-26-8 chemical structure

Description

As a certified reference material (CRM), Pitolisant Impurity 50 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.

CATO supplies Pitolisant Impurity 50 (CAS 90562-26-8), a pharmacopoeial impurity reference standard (molecular formula C9H10ClI, MW 280.53 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Pitolisant Impurity 50 (C9H10ClI) contains chlorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 280.53 g/mol, it falls into the medium-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.
