1.Product Property
Dimethylamine aqueous solution is a colorless, strongly alkaline liquid with a penetrating fishy or ammonia-like odor. It is completely miscible with water and ethanol, has a boiling point of ~51 °C, a density near 0.9 g cm⁻³ at 20 °C, and evolves flammable vapours heavier than air

3.Application Scope and Usage
The 40 % solution is a convenient source of dimethylamine for synthesis. It is widely used as a building block for dimethylformamide, dimethylacetamide and rubber accelerators; acts as a basic catalyst in condensation and alkylation reactions; serves as a pH regulator in water treatment, and is an intermediate for agrochemicals, pharmaceuticals and textile auxiliaries .
4.Package and Storage
Dimethylamine aqueous solution is supplied in HDPE drums of 200 kg net or 1000 L IBC totes. Small lots are available in 25 kg or 50 kg fluorinated HDPE jerricans. Store in a cool, shaded, well-ventilated area at 2 – 30 °C, away from acids, oxidisers, aluminium, copper and zinc. Keep containers tightly closed and avoid direct sunlight to prevent pressure build-up and corrosion .
