Although the 2, 3 -cyclic phosphates of adenosine, cytidine, guano-sine, and uridine appear to be stable in aqueous solution between, approximately, pH 4 and 9, they are hydrolyzed under more-strenuous conditions (for example, 0.1M hydrochloric acid for 1 hour at room temperature or 0.5 M sodium hydroxide for 12 hours at 37°) to give a mixture of 2 - and 3 -phosphates287 in approximately equal amounts. An appreciation of this aspect of the chemistry of cyclic phosphates was of considerable importance in elucidating the mechanism of the chemical degradation of ribonucleic acid.288...
