A sensitive gas chromatographichass spectrometric assay for paracetamol, produced by the 0-deethylation of phenacetin by microsomal fractions of human liver, has been developed. The method uses the 3,5-bistrifluoromethylbenzoyl derivative of paracetamol and electron capture negative ion chemical ion
