3-Dimethylaminopropylamine (DMAPA, CAS 109-55-7) is a bifunctional aliphatic amine containing both a primary amine and a tertiary dimethylamino group. It is widely used as an intermediate in production of amine-based surfactants, as a building block for polymer and resin modifiers, and as a reactive component in specialty formulations requiring nucleophilic/alkaline functionality. Commercial supply is offered in industrial, technical and reagent grades, with lot-specific Certificates of Analysis to support quality control.
3-Dimethylaminopropylamine; DMAPA; N-(3-Aminopropyl)dimethylamine; 3-(Dimethylamino)propylamine
| Property | Value |
|---|---|
| CAS Number | 109-55-7 |
| Molecular formula | C₅H₁₄N₂ |
| Molecular weight | ≈ 102.18 g*mol⁻¹ |
| EINECS / EC No. | (refer to supplier COA for exact EC listing per region) |
| Appearance | Colourless to pale yellow clear liquid; amine odor |
| Melting point / Freezing point | Liquid at ambient temperature; low freezing point (refer to COA) |
| Boiling point | ~200 -210 °C (literature ranges; batch/pressure dependent) |
| Density | ~0.78 -0.80 g*cm⁻³ (20-25 °C; supplier to confirm on COA) |
| Solubility | Completely miscible with water; miscible with many polar organic solvents |
| Flash point | ~77 -95 °C (closed cup; method-dependent) |
| pKa (conjugate acids) | Primary amine and tertiary dimethylamino site; typical conjugate-acid pKa values in the basic region (refer to technical literature/COA for exact values) |
Surfactant intermediate and quaternary ammonium precursor
Used to produce amine-based surfactants and tertiary-amine intermediates; readily quaternized to form stable cationic surfactants and fabric-care actives.
Epoxy curing and crosslinking agent modifier
Employed as a reactive component or accelerator in epoxy formulations and crosslinking systems, providing amine curing sites and tertiary-amine catalytic activity.
Chelating agent and corrosion inhibitor precursor
Used as a building block in synthesis of chelating ligands and corrosion inhibitor molecules for industrial water treatment and metal protection chemistry.
Polyurethane and resin modifiers
Applied in formulations as an intermediate or chain-extender/modifier in specialty polyurethanes, polyureas and resin systems.
Pharmaceutical & agrochemical intermediate (non-final API use)
Serves as an intermediate for fine chemical syntheses and protected-chemistry routes (for industrial intermediates rather than finished pharmaceutical APIs).
Analytical & laboratory reagent
Provided in small packs for R&D, synthetic method development and analytical reference use.
N-Methyldiethanolamine -- CAS 105-59-9; 3-Aminopropyltriethoxysilane (APTES) -- CAS 919-30-2; Ethylenediamine -- CAS 107-15-3; Diethylenetriamine -- CAS 111-40-0; 2-Dimethylaminoethanol -- CAS 108-01-0; N-(3-Aminopropyl)morpholine -- CAS 109-61-5; Triethylenetetramine -- CAS 112-24-3; 3-Aminopropylamine -- CAS 109-75-1; Dimethylamine -- CAS 124-40-3; N-Etherified/alkoxylated DMAPA derivatives (various CAS).
