: ADENOSINES',5l-PHOSPHATE (cyclic AMP), free acid : see insert in spectrum; C^H^NgOgP; MW = 329 : Serva, Heidelberg, GFR : suspension in methanol, 10 yg : standard : 4 X 104
remarks - This spectrum closely resembles that of 3'-AMP (Spectrum C.5), al-' though the intensity of the peak at m/z 114 appears to be further reduced, possibly as a result of blocking of the elimination of the ribose moiety from the molecule described by Posthumus et al. (ref. 72).
