2,5-DIMERCAPTO-1,3,4-THIADIAZOLE DIPOTASSIUM SALT Usage And Synthesis

Chemical Properties

white to light beige crystalline chunks or powder

Uses

thiadiazole pharmaceutical intermediate

Uses

1,3,4-thiadiazole-2,5-dithiol (Bismuthiol I) was used in determination of tellurium in indium phosphide doped with cadmium telluride by electro thermal atomic absorption spectrometry. It forms polymers with metals and can be useful in treatment of metal-polluted water.

General Description

1,3,4-thiadiazole-2,5-dithiol undergoes copolymerization with 1+, 2+ and 3+ valent metals to form coordination polymers. It forms polymers with metals and can be useful in treatment of metal-polluted water.

Purification Methods

Usually contaminated with disulfide. Purify it by recrystallisation from EtOH. It is a reagent for the detection of Bi, Cu, Pb and Sb. [Najumdar & Chacraborty Anal Chim Acta 19 372 1958, Fries Z Anal Chem 165 100, 1959, Beilstein 27 IV 7725.]
