Dimethylamine (DMA), CAS No. 124-40-3, is an important secondary amine widely used as a chemical intermediate across pharmaceutical, agrochemical, rubber, water treatment and specialty chemical industries.
With the molecular formula (CH₃)₂NH and a molecular weight of 45.08 g/mol, dimethylamine is commercially available both as anhydrous dimethylamine and in various aqueous solution concentrations, allowing chemical manufacturers to select an appropriate grade according to their production process and handling requirements.
Understanding Anhydrous Dimethylamine
Anhydrous dimethylamine is a high-purity form of DMA commonly supplied as a liquefied gas under pressure.
Reference technical data published by Sigma-Aldrich for anhydrous dimethylamine lists a purity of ≥99%, CAS No. 124-40-3, molecular weight 45.08, and a boiling point of approximately 7°C. The reference product is described as an anhydrous grade supplied in gas/liquid form.
Because of its relatively low boiling point and high volatility, appropriate equipment, pressure-rated packaging, ventilation and temperature control are important when storing and handling anhydrous DMA.
For industrial buyers, the selection between anhydrous DMA and an aqueous dimethylamine solution normally depends on the downstream reaction, required concentration, transportation conditions and plant handling system.
Dimethylamine Aqueous Solutions
In addition to anhydrous DMA, dimethylamine is widely supplied as a solution in water.
China Amines currently supplies multiple Dimethylamine grades, including:
- Dimethylamine Anhydrous
- Dimethylamine 40% Solution
- Dimethylamine 50% Solution
- Dimethylamine 60% Solution
- Custom concentrations subject to customer requirements
These different concentrations allow manufacturers to select DMA according to their reaction conditions, production equipment and downstream processing requirements.
For many industrial applications, aqueous DMA can offer more convenient handling compared with anhydrous liquefied gas while still providing dimethylamine as the active raw material.
Key Industrial Applications of Dimethylamine
Dimethylamine is an important building block in organic synthesis and is used in the production of a broad range of downstream chemicals.
1. Pharmaceutical Intermediates
DMA is widely used as a raw material or intermediate in pharmaceutical synthesis. It can also be converted into Dimethylamine Hydrochloride (DMA HCl), another important intermediate used by pharmaceutical and fine chemical manufacturers.
2. DMF and DMAC Production
Dimethylamine is an important upstream raw material used in the manufacture of Dimethylformamide (DMF) and Dimethylacetamide (DMAC), both widely used industrial solvents and chemical intermediates.
3. Agrochemicals
DMA and its derivatives are used in the manufacture of various pesticides, fungicides and other crop-protection intermediates.
4. Rubber Chemicals
The rubber industry uses dimethylamine-derived chemicals in the production of rubber accelerators and other processing chemicals.
5. Water Treatment Chemicals
Dimethylamine is also used as an intermediate for certain water treatment chemicals and functional polymers used in industrial and municipal water-treatment processes.
6. Specialty Chemical Synthesis
As a reactive secondary amine, DMA is an important intermediate for specialty amines, solvents, dyes, pigments and numerous other organic chemicals.
Sigma-Aldrich also references dimethylamine in several organic synthesis routes, further demonstrating its usefulness as a versatile secondary-amine building block.

Technical values should always be confirmed against the specification and COA for the actual batch supplied. Reference data for anhydrous DMA may vary slightly depending on test method and product specification.
Safety and Handling of Dimethylamine
Dimethylamine requires careful handling.
Reference safety information for anhydrous dimethylamine classifies the material as a highly flammable gas and a liquefied gas under pressure. It may also cause skin, eye and respiratory irritation. Appropriate personal protective equipment, ventilation and control of ignition sources are therefore essential.
Customers should always review the latest Safety Data Sheet (SDS/MSDS) before transportation, storage or use and ensure that handling procedures comply with applicable local regulations.
