CAS 2084-18-6: 3-Methyl-2-butanethiol
Description:3-Methyl-2-butanethiol, also known as tert-amyl mercaptan, is an organic compound characterized by its thiol functional group (-SH) attached to a branched carbon chain. It has a molecular formula of C5H12S and features a distinctive, strong odor often described as skunky or garlic-like, which makes it useful as an odorant in natural gas to detect leaks. This compound is a colorless liquid at room temperature and is slightly soluble in water, but more soluble in organic solvents. Its boiling point is relatively low, indicating it can easily evaporate. 3-Methyl-2-butanethiol is primarily used in the synthesis of various chemicals and as a flavoring agent in the food industry, although its strong odor limits its direct use in food products. Additionally, it is important to handle this substance with care due to its potential irritant properties and the need for proper ventilation when working with it in laboratory or industrial settings.
