Ethanethiol is the organic compound with the formula CH3CH2SH. It consists of an ethyl group, CH3CH2, abbreviated Et, attached to a thiol group, SH, and the entire molecule is often abbreviated EtSH.he compound is structurally similar to ethanol by replacement of O by S. This change leads to many different properties, the most infamous of which is the strong odour of EtSH. Ethanethiol is also more volatile than ethanol due to its diminished ability to engage in hydrogen bonding.
