From: Adenine oxidation by pyrite-generated hydroxyl radicals
Selected ion chromatographs in negative-ion electrospray for reactions of adenine with Fenton reagents and in presence of pyrite. Two products result from the oxidation of adenine, 2-hydroxyadenine and 8-oxoadenine. Also indicated are the calculated accurate masses of each analyte and the difference when compared with the measured mass of the depronated parent ions.
