Acid-base behavior of an oligomer of 3-amino-1,2,4-triazole

We report the acid-base behavior of OATA, an oligomer synthesized from 3-amino-1,2,4-triazole (ATA). We analyze the UV-vis spectroscopy at different media, and we analyze and discuss the acid-base equilibria taking into account tautomeric equilibria at different pH. The low aqueous solubility at neu...
