Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block for bioactive molecules due to its rigid heterocyclic structure, which enhances binding selectivity in drug-receptor interactions. Commonly employed in the preparation of serotonin and dopamine receptor modulators. Also utilized in the design of novel antidepressants and antipsychotic compounds. Its amine functionality allows for easy derivatization, making it valuable in medicinal chemistry for structure-activity relationship (SAR) studies.
