Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anti-inflammatory agents. Its acetonide structure provides stability to sensitive functional groups during multi-step reactions, making it valuable in protecting hydroxyl groups in complex organic syntheses. Commonly employed in the preparation of nucleoside analogs and steroid derivatives where selective protection is required. Also utilized in research settings for modifying bioactive molecules to enhance metabolic stability and bioavailability.
