Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its strained cyclobutane ring with a fluorine substituent enhances metabolic stability and influences binding affinity in medicinal chemistry. Commonly employed in the preparation of protease inhibitors, kinase inhibitors, and central nervous system agents. The amine functionality allows for easy derivatization, making it valuable in building complex organic molecules during drug discovery and process chemistry.
