Additional information

For the substance TMT six pKa values (three dissociation steps of 1,2,5-triazine-2,4,6-trithione in the pH range above 5 and three steps of protonation of the amino groups in strong acid pH regions) were estimated using ACD/LogD Suite Program: 10.37, 8.9, 6.35, 0.2, -1.25 and -3.3. Values from literature (11.38, 8.36, 5.71) are slightly different.
