It is prepared by reduction of 1,8-dinitronaphthalene, which in turn is obtained as a mixture of isomers by nitration of 1-nitronaphthalene.

Upon treatment with phthalic anhydride derivatives, the diamine converts to phthaloperinones.
The derivative from phthalic anhydride itself, Solvent Orange 60, is a useful orange pigment.
It is a precursor to 1,8-bis(dimethylamino)naphthalene.
