Chemical Structure
Description
Based on its molecular formula C20H18ClFPCl, (2-chloro-6-fluorobenzyl)(methyl)diphenylphosphonium chloride contains organophosphorus functionality, fluorine/chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 379.24 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.
