trime

Trime, also known as methanethiol, is an organosulfur compound with the chemical formula CH3SH. It is a colorless gas with a very strong, unpleasant odor, often described as resembling rotten cabbage. Trime is a naturally occurring substance and is produced by the decomposition of organic matter. It is also a byproduct of certain industrial processes, such as the Kraft process for pulping wood and the processing of natural gas.

The odor of trime is detectable at very low concentrations, making it useful as an odorant for otherwise odorless gases like natural gas and propane, serving as a safety warning for leaks. Industrially, trime is used in the production of other chemicals, including methionine, an essential amino acid used in animal feed, and as a precursor in the synthesis of pesticides and pharmaceuticals.

In biological systems, trime is produced by bacteria in the digestive tract and is also found in some foods, contributing to their characteristic smells. While its odor is generally considered offensive, it plays a role in various natural cycles and industrial applications. Its high volatility and distinct smell are its most notable characteristics.
