Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system agents. Its structural features make it valuable for modifying pharmacokinetic properties in drug candidates, such as improving blood-brain barrier penetration. Commonly employed in the preparation of receptor modulators and enzyme inhibitors, especially in the design of serotonin and dopamine receptor ligands. Also utilized in medicinal chemistry for scaffold optimization due to its conformational flexibility and hydrogen bonding capability.
