The individual and combined oxidation of 5-mercapto-1,3,4-thiadiazolthione-2 (bismuthol I) and 3,3'-dimethoxybenzidine (o-dianisidine) by hydrogen peroxide catalyzed by horseradish peroxidase (pH 5,0) was studied. It was shown that bismuthol I is a substrate for peroxidase, which is competitive towards o-dianisidine. In

A simple spectrophotometric method is presented for the rapid determination of copper at a trace level using 2,5-dimercapto-1,3,4-thiadiazole (DMTD) as a new spectrophotometric reagent. The method is based on the reaction of non-absorbent DMTD in a slightly acidic (0.002-0.014 mol

2,5-Dimercapto-1,3,4-thiadiazol (DMTD) can bind on the surface of a gold electrode through the strong gold-sulfur interaction. The fabrication and electrochemical characteristics of the DMTD self-assembled monolayer (SAM)-modified gold electrode were investigated. The DMTD SAM electrode exhibited a significantly increased sensitivity.
