Used in the synthesis of pharmaceutical intermediates, particularly in the development of drugs targeting central nervous system disorders. Its structure supports the creation of bioactive molecules due to the presence of fused ring systems and functional groups that enhance binding to neurological receptors. Commonly employed in research settings for constructing complex organic frameworks in medicinal chemistry. Also utilized in the preparation of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant compounds during early-stage drug discovery.
