Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of anti-inflammatory and analgesic agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in solid-phase synthesis due to the carboxylic acid group, which facilitates attachment to resin supports. Also utilized in the preparation of prodrugs, where the tert-butyl ester moiety can be cleaved under mild acidic conditions to release the active compound.
