Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 352.24 g/mol gives (Pentafluorophenyl)diphenylphosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(Pentafluorophenyl)diphenylphosphine (CAS 5525-95-1) is a high-purity analytical reference standard with the molecular formula C18H10F5P and a molecular weight of 352.24 g/mol.
(Pentafluorophenyl)diphenylphosphine (C18H10F5P) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
