Dimethylamine is an organic compound with the formula CH 3 2 NH. This secondary amine is a colorless, flammable gas with an ammonia -like odor. In , an estimated , tons were produced industrially, \\\\\\\\\\\\\\\[5\\\\\\\\\\\\\\\] but it is also found as a natural product. The molecule consists of a nitrogen atom with two methyl substituents and one proton. Dimethylamine reacts with acids to form salts, such as dimethylamine hydrochloride, an odorless white solid with a melting point of Dimethylamine is produced by catalytic reaction of methanol and ammonia at elevated temperatures and high pressure: Dimethylamine is a precursor to several industrially significant compounds. The solvents dimethylformamide and dimethylacetamide are derived from dimethylamine. It is raw material for the production of many agrichemicals and pharmaceuticals , such as dimefox and diphenhydramine , respectively. The chemical weapon tabun is derived from dimethylamine. The surfactant lauryl dimethylamine oxide is found in soaps and cleaning compounds. Unsymmetrical dimethylhydrazine , a rocket fuel, is prepared from dimethylamine. The German cockroach utilizes dimethylamine as a pheromone for communication. It is an attractant for boll weevils. Dimethylamine undergoes nitrosation under weak acid conditions to give dimethylnitrosamine. This animal carcinogen has been detected and quantified in human urine samples and it may also arise from nitrosation of dimethylamine by nitrogen oxides present in acid rain in highly industrialized countries. Deprotonation of dimethylamine can be effected with organolithium compounds. This lithium amide has been used to prepare volatile metal complexes such as tetrakis dimethylamido titanium and pentakis dimethylamido tantalum.
