Chemical Structure

Ibuprofen Impurity 35 CAS 63444-56-4 chemical structure

Description

As a certified reference material (CRM), Ibuprofen Impurity 35 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 Ibuprofen Impurity 35 (CAS 63444-56-4), a pharmacopoeial impurity reference standard (molecular formula C12H16, MW 160.26 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ibuprofen Impurity 35 (C12H16) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 160.26 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.
