Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) that involve piperazine ring systems. Its structure allows for selective modifications, making it valuable in medicinal chemistry for creating derivatives with potential biological activity. Commonly employed in research settings for designing drugs targeting central nervous system disorders and metabolic diseases. Also utilized in the preparation of protease inhibitors and receptor antagonists due to the stability and reactivity of the protected piperazine core.
