Progress in and Prospects for the Use of Heterocyclic Azo-compounds in Analytical Chemistry

The effects of substituents in bases and coupling components on the properties of heterocyclic azo-compounds are examined in the pyridine, anabasine, thiazole, quinoline, and antipyrine series and their compounds with metal ions. Methods are indicated for varying the sensitivity of the reagents, the stability of the resulting complexes, and the selectivity of reactions with inorganic ions. Prospects for the use of heterocyclic azo-compounds in analytical chemistry are noted.
