1H-1,2,4-Triazole-3-thiol Usage And Synthesis

Chemical Properties

WHITE TO SLIGHTLY YELLOW FINE CRYSTALLINE POWDER

Uses

1H-1,2,4-Triazole-3-thiol was used in a study to design a surface enhanced Raman scattering based probe for fast and accurate detection of DNA markers.

General Description

1H-1,2,4-Triazole-3-thiol is a mercapto-substituted 1,2,4-triazole ligand and exhibits tautomerism in solution. 1H-1,2,4-Triazole-3-thiol forms novel luminescent polymers with cadmium(II) salts. 1H-1,2,4-Triazole-3-thiol undergoes regioselective S-alkylation to form a series of S-substituted derivatives.
