Used as a building block in pharmaceutical synthesis, particularly in the development of bioactive molecules where fluorine substitution enhances metabolic stability and binding affinity. Its strained cyclobutane ring enables unique conformational properties, making it valuable in medicinal chemistry for designing enzyme inhibitors and receptor modulators. Also employed in agrochemical research to improve compound lipophilicity and resistance to degradation. The carboxylic acid group allows for easy derivatization, facilitating incorporation into larger molecular structures.
