Used as a key intermediate in the synthesis of certain pharmaceutical compounds, particularly in the development of selective estrogen receptor modulators (SERMs). Its functional groups and stereochemistry make it valuable for constructing complex drug molecules with high specificity. Commonly employed in research settings for modifying bioactive compounds to enhance stability, bioavailability, or receptor binding affinity. Also utilized in the preparation of prodrugs where controlled release of active agents is required. Its acetyl-protected hydroxyl groups allow for stepwise deprotection and further chemical modifications in multi-step organic syntheses.
