Dimethylamine is a medium-strong alkaline colorless flammable gas. It is usually a 40% aqueous solution of dimethylamine. The current production process for preparing an aqueous solution of dimethylamine will inevitably be accompanied by trace amounts of monomethylamine, dimethylamine and Monomethylamine is a lower aliphatic amine. Dimethylamine aqueous solution is a common chemical product, which is widely used in the field of chemical production. Mainly used as rubber vulcanization accelerator, leather dehairing agent, medicine (antibacterial), pesticide, textile industry solvent, dye, explosive, propellant and raw material for organic intermediates such as dimethylhydrazine, N,N-dimethylformamide . Among them, dimethylamine consumed in dimethylformamide production accounted for 44.7% of the total consumption, pesticide production consumption accounted for 38.9%, and pharmaceutical production consumption accounted for 16.4%. At present, in the pharmaceutical industry, it has been widely used in the synthesis of meropenem, metformin hydrochloride and other drugs, and the content of monomethylamine has an important impact on the amination reaction and product quality.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a gas chromatography method for the detection of dimethylamine in aqueous solution, which is simple to operate, sensitive, rapid, low-cost, and accurate and reliable in results.
