Chemical Structure
Description
As a certified reference material (CRM), Fenofibrate Impurity 15 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 Fenofibrate Impurity 15 (CAS 34183-01-2), a pharmacopoeial impurity reference standard (molecular formula C13H8Cl2O2, MW 267.11 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C13H8Cl2O2, Fenofibrate Impurity 15 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.11 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).
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.
