2-MERCAPTOIMIDAZOLE Chemical Properties,Usage,Production

Chemical Properties

White to light brown solid

Uses

2-Mercaptoimidazole has been used in chemical modification of silica gel for selective separation of mercury(II) from an aqueous solution.

General Description

The kinetics of inhibition on mushroom tyrosinase by 2-mercaptoimidazole has been investigated. The pH dependent surface-enhanced Raman scattering (SERS) spectra of biologically and industrially significant, 2-mercaptoimidazole molecule at 1.0×10^-10M concentration have been investigated.

Purification Methods

Crystallise 2-mercaptoimidazole from Me2CO or H2O. UV: at 208 and 252nm (H2O). max [Fox et al. J Am Chem Soc 67 496 1947, Beilstein 24 II 7, 24 III/IV 61.]
