Abstract

The synthesis and properties of 4,5,6,7-tetrahydroindazol-3-
-one-5,5-dicarboxylic acid (HIDA, I), its diammonium, II, and
monoammonium salt, III, are described. The concentration stability
constants of HIDA with Be++, Mg++, Ca++, Sr++, Ba++, Cu++, Co++,
Mn++, Zn++, and Cd++ are reported.
The potentiometric titration curves and UV and IR absorption
data are recorded.
