Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective modification, making it valuable in drug discovery programs targeting neurological disorders and cancer. Commonly employed in medicinal chemistry for building complex heterocyclic systems due to its reactive bromo group and functionalized piperazine ring. Also utilized in research settings to design potent and selective receptor agonists or antagonists.
