Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and central nervous system agents. Its oxetane ring contributes to improved metabolic stability and solubility in drug candidates. The hydroxyl and amine functional groups allow for further chemical modifications, making it valuable in medicinal chemistry for building complex molecules. It is also employed in the preparation of protease inhibitors and other bioactive compounds where ring structures with specific polarity are required.
