N,N-Dimethyl-1,3-propanediamine, 99%

Description

CAS: 109-55-7 | C5H14N2 | 102.181 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
