Used in the synthesis of selective estrogen receptor modulators (SERMs), particularly for the development of drugs targeting hormone-dependent conditions such as breast cancer and osteoporosis. It serves as a key intermediate in creating compounds with tissue-specific estrogenic activity, allowing for therapeutic effects on bone and cardiovascular systems while minimizing risks in breast and uterine tissues. Its structure supports high receptor binding affinity and metabolic stability, making it valuable in pharmaceutical research and development of novel endocrine therapies.
