WebApr 12, 2024 · TC is an amphoteric molecule and has three different acidic constants (pKa 1 = 3.30, pKa 2 = 7.7, and pKa 3 = 9.80). At different pH values, the different ionizing functional groups of TC have different pKa values. TC exists as a cationic molecule (TCH 3 + and TCH 2 +), because of the protonation of the dimethyl ammonium group, at pH ˂ 3.3.
