Dissociation constants of thymolphthalexone
Talanta, 1979For the dissociation constants of thymolphthalexone the following values have been found: pK(3) = 7.03 +/- 0.02, pK(4) = 8.05 +/- 0.09 (by potentiometric titration), pK(5) = 10.83 +/- 0.10, pK(6) = 12.99 +/- 0.11 (by spectrophotometry). They were determined at I = 0.4 and at 25 degrees.

Dissociation constants of arsenazo III
Talanta, 1986Commercial samples of Arsenazo III were found to be appreciably impure even after purification as the barium salt. Chromatography on silica gel followed by crystallization yielded a pure sample of the ethanol solvate of the free acid. The dissociation constants of the acid were determined potentiometrically at 25 degrees and I = 0.1 (NaClO(4)).

Dissociation constants of carboxymethyloxysuccinic acid
Talanta, 1974The dissociation constants of carboxymethyloxysuccinic acid (CMOS) have been measured at 25 degrees and an ionic strength of 0.1M in sodium perchlorate. The values found were: pK(1) = 2.52, pK(2) = 3.77 and pK(3) = 5.00. CMOS is thus seen to be rather stronger than its isomer citric acid.

Acid Dissociation Constants of Phenylalkanolamines
Journal of Pharmaceutical Sciences, 1962The acid dissociation constants of phenylephrine, synephrine, and tyramine were investigated by the new spectrophotometric method of Edsall. Epinephrine was studied by a titration and complexation method. It is concluded from analysis of the spectral data that the phenolic function is a stronger acid than the alkylammonium group.
