1,2-Diphenylethylenediamine is a chiral molecule, generally used as a chiral resolving agent and as a precursor of the chiral auxiliary. It is also used as a chiral solvating agent in NMR study.

The current preparation method is to split ()-1,2-diphenylethylenediamine under ethanol solvent with tartaric acid as the splitting agent, and according to the demand, the splitting is carried out by adopting different splitting conditions, so as to produce either (1S,2S)-1,2-diphenylethylenediamine or (1R,2R)- 1,2 -diphenylethylenediamine.
