Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. Its rigid bicyclic structure makes it valuable for designing bioactive molecules with improved metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates for pain management and neurological conditions. Also utilized in the preparation of prodrugs due to the presence of carboxylic acid functional groups that can be modified for enhanced bioavailability.
