Synthesis of 1, 2, 4-triazole benzoyl arylamine derivatives and their high antifungal activities.
European journal of medicinal chemistry, 2020Two series of novel 1, 2, 4-triazole benzoyl arylamine derivatives were prepared and screened for their activities against three pathogens of Gaeumannomyces graminis var.tritici, Sclerotinia sclerotiorum and Fusarium graminearum using the mycelium growth

3-Amyl-4-amino-1,2,4-triazole-5-thione (AATT) reacted with Cu2+ or Pb2+ ions in aqueous solutions to form CuAATT and Pb(AATT)2 complexes and their solubility product constants were measured as 10−16.17 and 10-20.60, respectively.

Althouth many C-aldehydes of azoles and azines, including those of 1,2,3-triazoles, are known and readily obtainable, free aldehydes derived from 1,2,4-triazole do not appear to have been isolated previously. The main aim of the work submitted in this thesis was the synthesis of such 1,2,4-triazole-C-aldehydes.

Reaction of 3-amino-1:2:4-triazole with lactoperoxidase
Archives of Biochemistry and Biophysics, 1973Bovine lactoperoxidase (LPO) gradually lost its enzymatic activity when dialyzed against a solution of 3-amino-1:2:4-triazole (AT) and hydrogen peroxide at pH 7.0. Amino acid analysis of the completely inactive enzyme revealed the formation of a new ninhydrin-positive chromatographic peak.

Synthesis of some nitro and amino derivatives of 1, 2, 4-triazole-5-thiones and 1, 2, 4-triazoles
Chemistry of Heterocyclic Compounds, 1967Isomeric 3-(nitrophenyl)-1, 2, 4-triazole-5-thiones are synthesized by cyclizing 1-nitrobenzoylthiosemicarbazides. 1-(4-Nitrophenyl)-1, 2, 4-triazole-3-thione is prepared by condensing 4-(4-nitrophenyl) thiosemicarbazide with formic acid. Oxidation converts the triazolethiones to nitrophenyltriazoles, and the latter are reduced to aminophenyltriazoles.

Synthesis of 5-amino-1-(aminothioformyl)-1, 2, 4-triazoles
Chemistry of Heterocyclic Compounds, 1971By the reaction of 5-amino-1, 2, 4-triazoles with benzoyl isothiocyanate we have synthesized 5-amino-1-(benzoylaminothioformyl)-1, 2, 4-triazoles, which form 5-amino-1-(aminothioformyl)-1, 2, 4-triazoles on alkaline hydrolysis.

1 : 2 : 4-triazole as a corrosion inhibitor for copper
Corrosion Science, 1980Abstract The solution chemistry of 1 : 2 : 4-triazole (TRZ) is investigated in the range of solution concentrations in which the compound acts as a corrosion inhibitor for copper. Parallel photo-electron spectroscopic studies show that although a surface layer of Cu(I) complex is formed at low TRZ concentrations, this is ineffective as an inhibitor ...

Basicity and structure of 1, 2, 4-triazole derivatives
Chemistry of Heterocyclic Compounds, 1967Basicity constants for a number of 1, 2, 4-triazole derivatives are determined. An assumed amine structure for 3-amino-1, 2, 4-triazoles in aqueous solution is demonstrated. It is assumed that protonization of 3- and 4-amino-1, 2, 4-triazoles occurs at the nitrogen in the heterocyclic ring, and not at the amino group.
