Twelve purines oxidized with 4,5-dimethyl-o-phenylenediamine (DMPD) was found to react with N-bromosuccinimide (NBS) to give fluorescent derivatives. In this paper, the identification of oxidation and fluorescent products have been described. In compliance with the substituent on purine skelton, three alloxans
