Tert-Butylthiol

Tert-Butylthiol

Tert-Butylthiol, also known as 2-methylpropane-2-thiol, is a type of organosulfur compound. This colorless liquid is a powerful stench agent and an additive in natural gas. Its structural formula is (CH3)3CSH.

Chemical Properties

Tert-Butylthiol is a thiol and an alkane. It is a member of the class of compounds known as tertiary alkanethiols. These are alkanethiols in which the sulfur atom is linked to a tertiary carbon atom. It has a sulfurous odor and is less dense than water.

Synthesis

Tert-Butylthiol can be synthesized through the reaction of tert-butyl alcohol with hydrogen sulfide in the presence of an acid catalyst.

Uses

Tert-Butylthiol is primarily used as an odorant for natural gas, which is odorless. The strong, unpleasant smell helps detect gas leaks. It is also used in the synthesis of other chemical compounds.

Safety

Exposure to tert-butylthiol can cause irritation to the eyes, skin, and respiratory tract. It is harmful if swallowed or inhaled, and may cause damage to the central nervous system.
