Compared with other compounds in its class, the molecular weight of 200.25 g/mol gives Flurbiprofen Impurity 12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Flurbiprofen Impurity 12 (CAS 55258-76-9), a pharmacopoeial impurity reference standard (molecular formula C14H13F, MW 200.25 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C14H13F, Flurbiprofen Impurity 12 contains fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 12 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.
