Abstract: Structures and chemical equilibria of 5-carboxy-2-thiouracil (1), 5,6-diphenyl-3-hydroxy-1,2,4-triazine (2), 1-phenyl-3-methyl-5-pyrazolone (3) and 2-mercapto-4,6-dimethylpyrimidine hydrochloride (4) are reported. Their electronic transitions are assigned and pK values are evaluated and discussed.
Keywords: Chemical equilibria; 5-carboxy-2-thiouracil; synthesis; electronic transitions and pK values Chemical equilibria; 5-carboxy-2-thiouracil; synthesis; electronic transitions and pK values
