TMA
Trimethylamine is an organic compound with the formula N(CH3)3. This colorless, hygroscopic, and flammable tertiary amine has a strong "fishy" odor in low concentrations and an ammonia-like odor at higher concentrations. It is a gas at room temperature but is usually sold in pressurized gas cylinders or as a 40% solution in water.
Trimethylamine is a product of decomposition of plants and animals. It is the substance mainly responsible for the odor often associated with fouling fish, some infections, and bad breath. It is also associated with taking large doses of choline and carnitine.
Trimethylamine is a nitrogenous base and can be readily protonated to give trimethylammonium cation. Trimethylammonium chloride is a hygroscopic colorless solid prepared from hydrochloric acid. Trimethylamine is a good nucleophile, and this reaction is the basis of most of its applications.
Applications
Trimethylamine is used in the synthesis of choline, tetramethylammonium hydroxide, plant growth regulators, strongly basic anion exchange resins, dye leveling agents and a number of basic dyes.[2][4] Gas sensors to test for fish freshness detect trimethylamine.
