Trifluoroacetyl chloride identified by the chemical formula C F 3 C O Cl is a highly reactive organic intermediate characterized by a molecular weight of 132 . 47 grams per mole and a boiling point of -27° degrees Celsius at standard atmospheric pressure existing as a colorless pungent gas at standard temperature and pressure while exhibiting a liquid density of 1 . 384 grams per cubic centimeter at -30° degrees Celsius and a melting point of -146° degrees Celsius the molecular geometry features a trifluoromethyl group attached to a carbonyl chloride moiety where the strong electron withdrawing nature of the 3 fluorine atoms increases the electrophilicity of the carbonyl carbon compared to non fluorinated analogs facilitating rapid nucleophilic substitution reactions such as esterification with alcohols to form trifluoroacetate esters and amidation with amines to produce trifluoroacetamides synthesis of trifluoroacetyl chloride is achieved through the chlorination of trifluoroacetic ac
