3-Amino-1,2,4-triazole (3-AT) is a heterocyclic organic compound that consists of 1,2,4-triazole with an amino group as a substituent. 3-AT is a competitive inhibitor of the product of the HIS3 gene, imidazoleglycerol-phosphate dehydratase. [3] [4] Imidazoleglycerol-phosphate dehydratase is an enzyme catalyzing the sixth step of histidine ...
1,2,3-benzothiadiazole is much less nucleophilic than naphthalene. Nitration is slow. [8] For that reason, many of its simple derivatives have been made from 2-aminothiophenols already having additional substituents. [7] 1,2,3-benzothiadiazole is a very weak base and alkylation reactions give exclusively the 3-amino quaternary salt. [9]
1,2,4-Triazole (as ligand in coordination compounds, Htrz abbreviation is sometimes used) is one of a pair of isomeric chemical compounds with molecular formula C 2 H 3 N 3, called triazoles, which have a five-membered ring of two carbon atoms and three nitrogen atoms. 1,2,4-Triazole and its derivatives find use in a wide variety of applications.

The 2H-1,2,3-triazole tautomer is the major form in aqueous solution. [6] It is a surprisingly stable structure compared to other organic compounds with three adjacent nitrogen atoms. However, flash vacuum pyrolysis at 500 °C leads to loss of molecular nitrogen (N 2 ) leaving a three-member aziridine ring.
