The mixture is a colorless, corrosive liquid, although older samples can appear yellow.

The two trans enantiomers can be resolved by conversion to diastereomeric salts of various chiral acids.

[1] The product is an epoxy curing agent for use in Coatings, Adhesives, Sealants and Elastomers - CASE.

[3] It may also be reacted with diethyl maleate utilizing the Michael reaction to produce a polyaspartic compound of CAS number 481040-92-0.

[6] It also is used in downfield oil and gas wells where there is an acidic stream to prevent corrosion to the bore piles.
