Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its rigid cyclobutyl structure with a phenyl substituent makes it valuable for designing compounds with specific stereochemistry and receptor selectivity. Commonly employed in research related to GABA analogs and muscle relaxants. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its constrained aliphatic ring system that influences bioavailability and metabolic stability.
