Quality Control of 8-Bromoguanine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 8-Bromoguanine, is researched, Molecular C5H4BrN5O, CAS is 3066-84-0, about Electronic spectra of 8-bromoguanine and 8-bromoadenine. Author is Pandey, K. S.; Mishra, P. C..
Absorption and fluorescence spectra of oxygenated and UV-irradiated aqueous solutions of 8-bromoguanine (BG) and 8-bromoadenine (BA), and pH effect on the spectra were studied. Each of BG and BA seem to have an asym. double-well ground state, like the parent mols. guanine and adenine. A qual. comparison of BG and BA with guanine and adenine in these respects was made. BG is much less affected by oxygenation and UV irradiation than is guanine. BA is affected by such treatments, but to a smaller extent than adenine. The mechanism of interaction of oxygen with the mols. under UV irradiation and the possible significance of the results is discussed.
