- W2034217842 abstract "Abstract The reagents were synthesized by using pentan-2,4-dione as the coupling component with diazotized 4-aminoantipyrine or 2-aminothiazole. Two kinds of azo compounds were obtained under different conditions: 1-(4-antipyrinylazo)-1-(4-antipyrinylhydrazino)propan-2-one (Azonol A-1) and 3-(4-antipyrinylazo)pentan-2,4-dione (Azonol A-2) from 4-aminoantipyrine, and 1-(2-thiazolylazo)-1-(2-thiazolylhydrazino)propan-2-one (TAA-1) and 3-(2-thiazolylazo)pentan-2,4-dione (TAA-2) from 2-aminothiazole. The structure of Azonol A-1 was determined by single-crystal x-ray crystallography. The reactions of these reagents with various metal ions were examined. Azonol A-1 and TAA-1 form metal chelates at low pH values. Azonol A-1 is useful as a metallochromic indicator in titrations of bismuth with EDTA at pH 0.5–2, and as a spectrophotometric reagent for copper (II) (0.2–1.5 mg l−1) at pH 0.3–1.2." @default.
