Usage

General Description

2-Methyl-1-butanethiol, also known as 2-methylbutyl mercaptan, is a chemical compound with the formula C5H12S. It is a volatile, colorless liquid with a strong, unpleasant odor, similar to that of rotten cabbage or garlic, and is often used as an odorant in natural gas to aid in the detection of leaks. It is also found in small quantities in certain food products, such as cheese and beer, and is a byproduct of the bacterial breakdown of organic matter. In addition to its use as an odorant, 2-methyl-1-butanethiol is also employed as a flavoring agent in the food industry and as a chemical intermediate in the synthesis of other organic compounds. Due to its strong odor and potential toxicity, it is important to handle this chemical with caution and in accordance with proper safety guidelines.
