Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification, making it valuable in medicinal chemistry for constructing complex drug candidates. The Boc-protected piperazine group facilitates controlled deprotection and coupling reactions, enabling efficient incorporation into larger molecular frameworks. Commonly employed in research settings for designing compounds with potential anticancer, antiviral, or central nervous system activities.
