The occurrence of 1-(3-Chlorophenyl)-2-(triphenylphosphoranylidene)ethanone is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3-Chlorophenyl)-2-(triphenylphosphoranylidene)ethanone (CAS 56893-07-3) is a high-purity analytical reference standard with the molecular formula C26H20ClOP and a molecular weight of 414.86 g/mol.
1-(3-Chlorophenyl)-2-(triphenylphosphoranylidene)ethanone (C26H20ClOP) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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).
