Dimethylamine solution is typically a colorless, transparent liquid with a fishy odor (commercially available as a 30%-40% aqueous solution). It is volatile and miscible with water. As an aqueous solution of a secondary amine, its chemical properties are similar to those of anhydrous dimethylamine, exhibiting alkalinity, nucleophilicity, and methylation capability, while being more convenient for industrial storage and use. Its main applications include serving as an important organic synthesis intermediate and methylating agent, widely used in the production of pesticides (such as glyphosate), pharmaceuticals (such as antibiotics), ionic liquid surfactants (such as amine oxides), as well as functioning as a rubber accelerator, leather treatment agent, and organic synthesis solvent.
