Used in the synthesis of pharmaceutical intermediates, particularly in the development of selective estrogen receptor modulators (SERMs). It serves as a key building block in the preparation of compounds with potential therapeutic effects in hormone-related conditions, including osteoporosis and breast cancer. Its structural features allow for functionalization that enhances binding affinity to estrogen receptors, making it valuable in medicinal chemistry research. Also employed in the optimization of drug candidates due to its chiral centers and ability to influence metabolic stability.
