Inhibition of Cholinesterases by 1 : 2 : 4-Triazoles
Nature, 1955IT has been repeatedly observed in my laboratory that workers, including non-smokers, manipulating 1 : 2 : 4-triazoles develop symptoms of light nicotine or physostigmine poisoning from time to time. Subsequent experiments have shown that some simple water-soluble 1 : 2 : 4-triazoles may act as inhibitors of cholinesterase activity.

The preparation of N- and C-halogen derivatives of 1, 2, 4-triazole
Chemistry of Heterocyclic Compounds, 1972The action of halogens in an alkaline medium on 1, 2, 4-triazoles has given their N-chloro, N-bromo, and N-iodo derivatives. The formation of C-halogen derivatives of some 1, 2, 4-triazoles from their N-halogen derivatives has been studied, and also the action of halogens on 1, 2, 4-triazoles at elevated temperatures.

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 inhibition method in vitro.

Toxicity of 3‐Amino‐1: 2: 4‐Triazole to Activated Sludge Biomass [PDF]
Toxicological & Environmental Chemistry, 1984 3‐amino‐1: 2: 4‐triazole (AT), a potent weed killer, added to activated sludge, caused immediate and drastic reduction in oxygen uptake by biomass. AT, a known specific inhibitor of catalases of animal and plant sources, did not appreciably alter catalase of activated sludge biomass.

Die Röntgenstrukturanalyse von 1, 2, 4‐Triazol
Berichte der Bunsengesellschaft für physikalische Chemie, 1965AbstractDie Kristallstruktur von 1, 2, 4‐Triazol, C2N3H3, wurde durch dreidimensionale Analyse der Röntgenbeugungsdaten ermittelt. Die Kristalle sind rhombisch (Raumgruppe Pbca‐D152h) mit 8 Molekülen in der Elementarzelle. Die Gitterkonstanten haben die Werte: a = 9,69 ± 0,04 Å, b = 9,38 ± 0,04 Å, c = 7,14 ± 0,03 Å.

Synthesis of derivatives of 1, 2, 4-triazole-3, 5-dicarboxylic acid
Chemistry of Heterocyclic Compounds, 1972By oxidation of 3,5-dimethyl-1,2,4-triazole the monopotassium salt of 1,2,4-triazole-3,5-dicarboxylic acid was obtained. The mononitryl of 1,2,4-triazole-3,5-dicarboxylic acid was isolated during the reaction between 3-diazo-1,2,4-triazole-5-carboxylic acid and potassium cyanide in the presence of copper cyanide.

1, 2, 4-Triazol-3-one and its nitro and amino derivatives
Chemistry of Heterocyclic Compounds, 1967Some possible methods of preparation of 1, 2, 4-triazol-3-one are explored. A new method of preparing it from semicarbazide hydrochloride and formic acid is worked out. Nitration of the triazolone gives 5-nitro-1, 2, 3-triazol-3-one, whose structure is proved.

A new method of preparing 1, 2, 4-triazole carboxylic-3 acids
Chemistry of Heterocyclic Compounds, 1966A new convenient method of preparing 1, 2, 4-triazole carboxylic acids-3 is worked out. Aminoguanidine bicarbonate and oxalic acid give 5-amino-1, 2, 4-triazole carboxylic acid-3, and this is converted, via the diazotriazole carboxylic acid and treatment of the latter with methanol, to 1, 2, 4-triazole carboxylic-acid-3.
