Chemical Structure

Fenofibrate EP Impurity F CAS 154356-96-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.74 g/mol gives Fenofibrate EP Impurity F distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Fenofibrate EP Impurity F (CAS 154356-96-4) is a certified pharmaceutical impurity reference standard with the molecular formula C16H15ClO2 and a molecular weight of 274.74 g/mol.

Fenofibrate EP Impurity F (C16H15ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Fenofibrate EP Impurity F 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.
