It is the simplest organotellurium compound that has been purified in bulk.

A colorless gas, it decomposes to Te and methane near room temperature.

It is prepared by reduction of dimethyl ditelluride using Na/NH3 followed by protonation of the CH3Te−Na+ (sodium methanetellurolate) with sulfuric acid.

[1] Few publications describe this compound as a consequence of its instability and paucity of applications.

For the lighter homologues, νE-H = 2342 (E = Se), 2606 (E = S), and 3710 cm−1 (E = O) for methaneselenol, methanethiol, and methanol.
