Used as an intermediate in the synthesis of various pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure allows for alkylation reactions, making it valuable in creating active pharmaceutical ingredients (APIs) that require piperazine-based moieties. Commonly employed in research settings for the preparation of antipsychotics, antidepressants, and other bioactive molecules where a functionalized piperazine ring is needed. The hydrobromide salt enhances stability and solubility, facilitating handling and reaction efficiency in organic synthesis.
