Used primarily in organic synthesis as a building block for more complex chemical compounds, particularly in the development of pharmaceuticals. It serves as a key intermediate in the creation of various therapeutic agents, including those targeting neurological and psychiatric disorders. Its structure allows for the introduction of piperazine rings into molecules, which are often crucial for biological activity. Additionally, it is employed in research settings to study receptor interactions and drug mechanisms due to its reactive bromoethyl group, facilitating further chemical modifications.
