What is 3-Dimethylaminopropylamine?
3-Dimethylaminopropylamine (DMAPA) is a diamine used in the preparation of certain surfactants, such as coconut amidopropyl betaine, which is an ingredient of many personal care products, including soap, shampoo and cosmetics. BASF, the main manufacturer, claims that DMAPA derivatives do not hurt eyes and will produce fine foam, making them suitable for shampoo.
Diamines are an important class of chemical substances that are widely used as raw materials, intermediates or products. For example, diamines are necessary structural devices in the process of synthesizing polyamides and also in other polycondensation responses. N,N-Dimethyl-1,3-diaminopropane (DMAPA) is an important intermediate for industrial preparation such as lubricants, in addition, DMAPA is used as a raw material for the preparation of coagulants, which itself should have Corrosion resistance.
3-Dimethylaminopropylamine Uses
- 3-Dimethylaminopropylamine is widely used in the manufacture of cosmetic raw materials, such as palmamide dimethylpropylamine, cocamidopropyl betaine, mink oil amidopropylamine, etc.
- N,N-dimethyl-1,3-propanediamine is an intermediate of the fungicide propamocarb.
- 3-Dimethylaminopropylamine is used as an intermediate in organic synthesis to prepare dyes, ion exchange resins, epoxy resin curing agents, oils and additives for cyanide-free electro-galvanizing, fiber and leather treatment agents and fungicides.
- 3-Dimethylaminopropylamine contains both primary and tertiary amine groups in the molecule. It is used as epoxy resin curing agent with both functions of curing agent and accelerator. Mainly used for laminates, castings and adhesives, etc., the general dosage is 2-6 parts.

Application 1
CN201511019713.3 discloses an artemisinin derivative and a synthesis method and application thereof. The artemisinin derivative is N-(3-N’,N’-dimethylamino-propyl)-10-azadeoxyartemisinin, which uses artemisinin as a raw material and is successively mixed with N. , N-dimethyl-1,3-diaminopropane and p-toluenesulfonic acid reaction.
By investigating the proliferation inhibitory activity of the derivative on various human tumor cell lines and human normal cell lines, the applicant found that it can inhibit human bladder cancer cells T-24, human ovarian cancer cells SK-OV-3, and human gastric cancer cells MGC80- 3 All three cell lines showed significant proliferation inhibitory activity and had good potential medicinal value, and were expected to be used in the preparation of various anti-tumor drugs.
Application 2
CN201510025397.4 discloses a 1,8-naphthalimide derivative and a synthesis method and application thereof. The derivative is N-(3,4-methylenedioxyphenethyl)-4-(3-N,N-dimethylamino)propylamino-1,8-naphthalimide, which is The compound is obtained by reacting 4-bromo-1,8 naphthalene dicarboxylic anhydride with 3,4-methylenedioxyphenethylamine and N,N-dimethyl-1,3-diaminopropane successively. The synthesis method is simple and easy to control.
The applicant has investigated its proliferation inhibitory activity on 9 human tumor cell lines and two normal cell lines, and the results show that its in vitro anti-tumor activity is significant, has good potential medicinal value, and is expected to be used in various anti-tumor drugs. preparation.
Application 3
CN201911150842.4 discloses a preparation method of an amphiphilic polymer-modified ultrafiltration membrane, which belongs to the technical field of membrane separation. The specific scheme is as follows:
- By the condensation polymerization method, terephthaloyl chloride, 3,3′-dimethyl-4,4′-diaminodiphenylmethane and N,N-dimethyl-1,3-diaminopropane are dissolved together In the mixed solution of dimethylformamide and triethylamine, low temperature copolymerization is used to prepare polyamide polymer.
- The polyamide polymer is reacted with 1,3-propane sultone to obtain an amphiphilic zwitterionic polyamide.
- The amphiphilic zwitterionic polyamide and polysulfone are blended to obtain a casting liquid, and the ultrafiltration membrane is prepared by a non-solvent induced phase inversion method.
In the casting solution of organic solvent, the hydrophobic polyamide segment in the amphiphilic polymer is similar in polarity to polysulfone, which increases its compatibility. In the aqueous phase, the hydrophilic segments in the amphiphilic polymer are enriched on the membrane surface, which plays an antifouling effect.
