Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules with potential neurological and psychiatric applications. Its strained cyclobutanone ring combined with an amine functionality allows for selective derivatization, making it valuable in medicinal chemistry for constructing novel drug candidates. Commonly employed in ring-expansion reactions and as a building block in the preparation of conformationally constrained analogs of bioactive amines. Also utilized in the synthesis of gamma-aminobutyric acid (GABA) modulators and other central nervous system agents.
