Chemical Structure
Description
(2-Fluorobenzylidene)triphenyl-l5-phosphane (C25H20FP) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(2-Fluorobenzylidene)triphenyl-l5-phosphane (CAS 82757-27-5) is a high-purity analytical reference standard with the molecular formula C25H20FP and a molecular weight of 370.40 g/mol.
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.
As a certified reference material (CRM), (2-Fluorobenzylidene)triphenyl-l5-phosphane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
