: ADENOSINE-3'-PHOSPHATE (3'-AMP), free acid : see insert in spectrum; C-]oH14^5°7P; MW = 347 : Serva, Heidelberg, GFR : suspension in methanol, 10 yg : standard : 5 X 104

remarks - In comparison with the spectrum of 51-AMP (Spectrum C.3) the intensity of the peaks at m/z 85 and 114 is reduced whereas a markedly higher peak is observed at m/z 84. This indicates the strong influence of the position of the phosphate group on the pyrolytic fragmentation pathways.
