The mixture is a colorless solid, but typical samples are yellowish and oily.

The compound is produced as a mixture of three isomers by the hydrogenation of methylenedianiline.

[3] These isomers are, in decreasing order of their yield from the hydrogenation, trans-trans, cis-trans, and a small amount of cis-cis.

[4] This diamine is mainly used to make epoxy resin curing agents for CASE (Coatings, Adhesives, Sealants, and Elastomers) applications especially flooring.

[5] Another application arises from its reaction with phosgene to produce a cycloaliphatic diisocyanate Hydrogenated MDI, which is used to produce light stable polyurethanes.
