1,3-Diaminopropane, also known as trimethylenediamine, is a simplediamine with the formula H2N(CH2)3NH2. A colourless liquid with a fishy odor, it is soluble in water and many polar organic solvents. It is isomeric with1,2-diaminopropane. Both are building blocks in the synthesis ofheterocycles, such as those used intextile finishing, andcoordination complexes. It is prepared by the amination ofacrylonitrile followed byhydrogenation of the resultingaminopropionitrile.[1]
The potassium salt was used in thealkyne zipper reaction.[2]
Known uses of 1,3-diaminopropane are in the synthesis ofpiroxantrone andlosoxantrone.
1,3-Diaminopropane is toxic on skin exposure with anLD50 of 177 mg kg−1 (dermal, rabbit)
