I have generated a Mass Spectrum for PAracetamol extracted from a coproxamol tablet and analysed by GCMS. I see major peaks at m/z 43, 80, 109, 151. 151 is clearly the parent ion and 109 and 43 the fragments formed by the cleavage of the CO-NH bond. but I have no idea where the peak at m/z 80 comes from... can anyone help ? Thanks in Advance A
