China and the United States are the leading exporters of dimethylamine, accounting for a substantial share of global shipments, while India, South Korea, and Germany represent the largest importers. Dimethylamine prices have remained relatively stable amid steady cross-border flows, reflecting consistent demand from agrochemical and pharmaceutical manufacturing sectors. Export volumes from China increased modestly in 2023–2024, while U.S. exports held steady, and Indian imports rose notably—indicating strengthening regional downstream production capacity.
Dimethylamine is a colorless, volatile liquid with a strong, fishy, ammoniacal odor; it has a boiling point of 7°C and a melting point of −58°C. It is a secondary aliphatic amine and a key organic chemical intermediate. Industrially, it is primarily used in the synthesis of dimethylformamide (DMF), rubber accelerators (e.g., CBS and TBBS), agrochemicals (including herbicides and plant growth regulators), and pharmaceuticals (e.g., ranitidine precursors). Its applications span agrochemicals, pharmaceuticals, elastomers, and surfactants, where it serves as a building block for quaternary ammonium compounds and chelating agents.
Dimethylamine is used in the manufactureof N-methylformamide, N-methylacetamide,and detergent soaps; in tanning; and as anaccelerator in vulcanizing rubber. It is commercially sold as a compressed liquid intubes or as a 33% aqueous solution..
Dimethylamine reacts readily with acids to produce salts due to the presence of the unshared electron pair on the nitrogen atom. Similarly, dimethylamine reacts with acid anhydrides, halides, and esters, with CO2 or CS2, or with isocyanic or isothiocyanic acid derivatives. It can also react with nitrite, especially under acidic conditions, and possibly nitrogen oxides (Iqbel 1986) to form N-nitrosodimethylamine, a potent carcinogen in various animal species and a suspect human carcinogen (ATSDR 1989; Scanlan 1983; Zeisel et al 1988). N-Nitrosodimethylamine also can be formed upon storage of aqueous dimethylamine solutions or formulations of the dimethylamine salts of the herbicides 2,4D and MCPA (Wigfield and McLenaghan 1987a,b). Dimethylamine also can be nitrosated photochemically in aqueous solutions containing nitrite with the reaction occurring most readily at alkaline pH (Ohta et al 1982).
