It has similar reactivity and uses as ethylenediamine and diethylenetriamine, with applications in epoxy curing.

Commercially available TETA contains 40% of the branched and cyclic isomers, N(CH₂CH₂NH₂)₃) and (CH₂CH₂NH)₃, respectively. In the area of coordination chemistry, these isomers are called TREN and TACN.

The hydrochloride salt, referred to as trientine hydrochloride, is a chelating agent used to remove excess copper from the body in Wilson's disease.^[1]
