Yes, that is the infamous 1-Benzylpiperazine.
In synthetic organic chemistry when you want to introduce a piperazine group somewhere, for example by reacting it with propenoic acid to get 3-(N-piperazinyl)-propanoic acid, you cannot simply mix piperazine with the acid, as it would add to both nitrogens, as the molecule is symmetric.
By instead starting with 1-Benzylpiperazine, add the acid to the free nitrogen, and finally remove the benzyl group by catalytic hydrogenolysis, the end product is 3-(N-piperazinyl)-propanoic acid without any contamination of the disubstituted analog.
