Trimethylamine - Wikipedia
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, … 展开
TMA is a colorless, hygroscopic, and flammable tertiary amine. It is a gas at room temperature but is usually sold as a 40% solution in water. It is also sold in pressurized gas cylinders.

The first dream of his own which Sigmund Freud tried to analyse in detail, when he was developing his theories about the interpretation of dreams, involved a patient of Freud's who had to have an injection of trimethylamine, and the chemical formula of the substance, written … 展开
1899Sigmund Freud had a dream involving a patient who had to have an injection of TMA.1930sTrimethylamine was used in the synthesis of choline, tetramethylammonium hydroxide, plant growth regulators, herbicides, and other products.2010sTrimethylamine N-oxide (TMAO) was investigated as a possible proatherogenic substance that may accelerate atherosclerosis.In humans, ingestion of certain plant and animal (e.g., red meat, egg yolk) food containing lecithin, choline, and L-carnitine provides certain gut microbiota with the substrate to synthesize TMA, which is then absorbed into the bloodstream. High levels … 展开

为什么N（CH3）3的偶极矩仅有0.67D？ - 知乎
在考虑偶极矩时，不仅要考虑电性。还要考虑电荷中心到分子中心的距离。三甲胺的负电中心接近于n中心。一相乘自然会变小。
