Used as a key intermediate in the synthesis of selective estrogen receptor modulators (SERMs), particularly in the development of certain anti-estrogenic pharmaceuticals for hormone-responsive conditions. Its structure enables effective binding modulation of estrogen receptors, making it valuable in treatments for breast cancer and osteoporosis. The compound’s cyanophenoxy and hydroxyphenyl acetamide groups contribute to receptor selectivity and metabolic stability, enhancing drug efficacy and tissue-specific action.
