Sign in to saveAlso known as TMA, N(CH3)3, NMe3, N,N,N-trimethylamine, tridimethylaminomethane, N,N-dimethyl-methanamine, trimethylamine anhydrous, N-trimethylamine
Trimethylamine (TMA) is an organic compound with the formula N(CH3)3. It is a trimethylated derivative of ammonia. TMA is widely used in industry. At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. At lower concentrations, it has a "fishy" odor, the odor associated with rotting fish.
