3-Dimethylaminopropylamine CAS#109-55-7
Dimethylaminopropylamine is an aliphatic amine present in amphoteric surfactants such as liquid soaps and shampoos. It is present as an impurity responsible for allergy from cocamidopropylbetaine. It is structurally similar to diethylaminopropylamine. It is also used as a curing agent for epoxy res ins and as an organic intermediate in chemical syntheses (ion exchangers, additives for flocculants, cosmetics and fuel additives, dyes and pesticides). |

Product Application Of 3-Dimethylaminopropylamine CAS#109-55-7
Useful for cleavage of N-alkylphthalimide derivatives to give primary amines, as an alternative to methyl hydrazine. DMAPA is also used directly as a hardener in epoxy resins in the plastics industry, as a cross linking agent for cellulose fibers in the paper industry and as an anti-shriking agent for leather. It is used as an intermediate in the production of binding agents, ion-exchange materials, flocculating agents (water treatment), cosmetic agents, washing and cleaning agents (betaines), additive for petrol and other fuels, polyurethane fibers and lubricants, dyes, agrochemicals, agents used in the photographic and textile industries. |
