Used as a key intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its rigid cyclobutane backbone and electron-withdrawing trifluoromethyl group enhance metabolic stability and binding selectivity, making it valuable in medicinal chemistry. Commonly employed in the preparation of protease inhibitors, receptor agonists, and anti-inflammatory agents. Also utilized in agrochemicals to improve the potency and environmental stability of active ingredients.
