Used in organic synthesis as a key intermediate for pharmaceuticals and natural product analogs. Its strained bicyclic framework and carboxylic acid functionality make it valuable in constructing complex ring systems. Commonly employed in cyclization reactions to build polycyclic structures found in bioactive molecules. Also applied in medicinal chemistry for developing serotonin receptor ligands and dopamine analogs due to structural similarity with neurotransmitter scaffolds. Shows potential in synthesizing CNS-active compounds and psychoactive drug candidates.
