Chemical Structure
Description
1-(3-Chloro-4-fluorophenyl)-2-phenylethan-1-one (C14H10ClFO) contains a hydroxyl group, an ether linkage, fluorine/chlorine 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).
1-(3-Chloro-4-fluorophenyl)-2-phenylethan-1-one (CAS 845781-19-3) is a high-purity analytical reference standard with the molecular formula C14H10ClFO and a molecular weight of 248.68 g/mol.
