3-Amino-5-mercapto-1,2,4-triazole Chemical Properties,Usage,Production

Uses

3-Amino-5-mercapto-1,2,4-triazole is used as a corrosion inhibitor. It can also be used as a reactant in the synthesis of triazole derivatives.

Chemical Properties

white to light beige crystalline powder

Uses

3-Amino-1,2,4-triazole-5-thiol was used to study the inhibition of corrosion of iron in 3.5% NaCl solutions by low concentrations of ATT and 1,1′-thiocarbonyldiimidazole. It was used to prepare surface-enhanced Raman scattering based pH nano- and microsensor using silver nanoparticles.

Uses

3-Amino-5-mercapto-1,2,4-triazole is used as a corrosion inhibitor. It can also be used as a reactant in the synthesis of triazole derivatives.

Synthesis Reference(s)

Journal of Heterocyclic Chemistry, 26, p. 355, 1989 DOI: 10.1002/jhet.5570260216

General Description

3-Amino-1,2,4-triazole-5-thiol inhibits corrosion of copper in aerated acidic chloride pickling solutions.

Purification Methods

Recrystallise the triazole from H2O and dry it in vacuo. The acetyl derivative has m 325o(dec) after recrystallisation from H2O. [Beilstein 26 III/IV 1351.] It has also been recrystallised from EtOH/H2O (3:1, 1g in 50 mL, 50% recovery), m 300-302o (dec subject to heating rate), ( max 263nm, log 4.12). The S-benzyl derivative, when crystallised from *C6H6/EtOH (20:1), or CHCl3/Et2O has m 109-111o [Godfrey & Kruzer J Chem Soc 3437 1960, Beilstein 26 III/IV 1351.]
