Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceutical compounds. The molecule features a piperazine core protected with a tert-butyl carbamate group on one nitrogen and a but-3-yn-1-yl chain on the other, providing a terminal alkyne handle for efficient functionalization via click chemistry reactions. This dual functionality allows for selective modifications, making it valuable in the development of bioactive molecules and drug candidates. The protecting group enables controlled reactions at other sites of the molecule. Commonly employed in medicinal chemistry for constructing complex amines and heterocyclic systems.
