Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where piperazine derivatives are required. Its functional groups allow for easy modification in multi-step organic reactions, making it valuable in drug discovery and development. Commonly employed in the production of central nervous system agents, antipsychotics, and antihistamines due to the biological activity associated with the piperazine core. Also utilized in the preparation of agrochemicals and specialty chemicals requiring nitrogen-containing heterocycles.
