Description and Uses
1,2-Diaminopropane is a colorless liquid that is very hygroscopic and miscible with water and most organic solvents. It forms azeotropes with butanol, 2-methylpropanol, and toluene and has a strong ammoniacal odor.
1,2-Diaminopropane was used as model precursor in the electron induced deposition of amorphous carbon nitride films.
