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.
Application
1,3,4-thiadiazole-2,5-dithiol (Bismuthiol I) was used in determination of tellurium in indium phosphide doped with cadmium telluride by electrothermal atomic absorption spectrometry.

Industrial lubricants are usually made of petroleum and contain no water. Industrial greases and neat oils (insoluble metalworking oils) cause contact allergy relatively seldom, and reported allergies to the components of engine oils, such as hydraulic oils, are extremely scarce.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
