2-Methyl-1-butanethiol, also known as isobutyl mercaptan, is an organic compound characterized by its thiol functional group (-SH) attached to a branched alkane chain. It has a molecular formula of C5H12S and features a distinctive, strong odor often described as skunky or similar to that of garlic. This compound is a colorless liquid at room temperature and is soluble in organic solvents but has limited solubility in water. Its boiling point is relatively low, which allows it to evaporate quickly. 2-Methyl-1-butanethiol is primarily used in the synthesis of various chemicals and as a flavoring agent in the food industry, although its strong odor can be a limiting factor. Additionally, it is utilized in the production of certain pharmaceuticals and as an intermediate in organic synthesis. Due to its potential for causing irritation, proper handling and safety precautions are essential when working with this compound.

Prepared from 2-methyl-1-butyl isothiourea picrate by conversion
to bis [(s)-2-methylbutyl] disulfide, followed by reduction to the 
corresponding thiol, using sodium metal in liquid ammonia.
