Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients requiring sterically hindered carboxylic acid groups. Its rigid cyclobutane ring and bulky tert-butyl group make it valuable in modifying drug stability, bioavailability, and metabolic resistance. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies and in the design of enzyme inhibitors. Also utilized in agrochemical research for creating novel compounds with enhanced selectivity and environmental stability.
