Fenofibrate Impurity 5 CAS 62810-39-3 chemical structure

Description

CATO manufactures Fenofibrate Impurity 5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Fenofibrate Impurity 5 (CAS 62810-39-3) is a certified pharmaceutical impurity reference standard with the molecular formula C13H9ClO2 and a molecular weight of 232.66 g/mol.

Structurally, Fenofibrate Impurity 5 (C13H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 232.66 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
