Used primarily as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its stereochemistry makes it valuable in the preparation of chiral compounds where specific spatial arrangement is crucial for biological activity. Commonly employed in the construction of complex molecules requiring piperazine rings with defined substituent orientation. Also utilized in research settings for designing bioactive molecules, including potential drug candidates targeting central nervous system disorders and antimicrobial agents. Its rigid structure and hydrogen-bonding capability support its use in molecular scaffolds for drug discovery.
