Ibuprofen EP Impurity R CAS 102120-87-6 chemical structure

Description

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.

CATO supplies Ibuprofen EP Impurity R (CAS 102120-87-6), a pharmacopoeial impurity reference standard (molecular formula C22H30, MW 294.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C22H30, Ibuprofen EP Impurity R contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 294.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Ibuprofen EP Impurity R 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.
