Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 454.57 g/mol gives Flurbiprofen Impurity 125 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Flurbiprofen Impurity 125 (CAS CATO-C4X-1444125) is a certified pharmaceutical impurity reference standard with the molecular formula C28H35FO4 and a molecular weight of 454.57 g/mol.
Flurbiprofen Impurity 125 (C28H35FO4) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Flurbiprofen Impurity 125 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.
