CAS 541-31-1: 3-Methyl-1-butanethiol

Description:3-Methyl-1-butanethiol, also known as isobutyl mercaptan, is an organic compound with the molecular formula C5H12S. It is characterized by a thiol functional group (-SH) attached to a branched alkane chain. This compound typically appears as a colorless to pale yellow liquid with a strong, unpleasant odor reminiscent of garlic or skunk, which makes it useful as an odorant in natural gas to detect leaks. It has a relatively low boiling point and is soluble in organic solvents but only slightly soluble in water. The presence of the thiol group imparts distinct chemical properties, including reactivity with oxidizing agents and the ability to form disulfides. 3-Methyl-1-butanethiol is used in various applications, including flavoring agents in the food industry and as a chemical intermediate in organic synthesis. Due to its strong odor, it is also studied for its potential effects on human health and environmental impact. Proper handling and storage are essential due to its volatility and potential irritant properties.
