Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its strained oxetane ring enhances metabolic stability and improves pharmacokinetic properties in drug candidates. Commonly employed in asymmetric synthesis due to its stereochemical purity, enabling precise control over the three-dimensional structure of complex molecules. Also utilized in the preparation of functionalized polymers and as an intermediate in agrochemicals.
