Dimethyl telluride

Dimethyltelluride is an organotelluride compound, formula (CH₃)₂Te, also known by the abbreviation DMTe.

This was the first material used to grow epitaxial cadmium telluride and mercury cadmium telluride using metalorganic vapour phase epitaxy. CAS registry number Template:CASREF.

Dimethyltelluride as a product of microbial metabolism was first dicovered in 1939. ^[1] Dimethyltelluride is produced by some fungi and bacteria (Penicillium brevicaule, P. chrysogenum, and P. notatum and the bacterium Pseudomonas fluorescens).^{[citation needed]}

It is highly toxic to humans and reacts violently with water. It is produced by the body when tellurium or one of its compounds are ingested. It is noticeable by its garlic-like smell. Anyone who has been working with or exposed to tellurium and exhibits this garlic-like smell on the breath, sweat or in the urine should remove themselves from the area. Tellurium is known to be toxic.
