Used in research for developing selective estrogen receptor modulators (SERMs) due to its structural affinity for estrogen receptors. Shows potential in studying hormone-related cancers, particularly breast cancer, by modulating estrogenic activity in tissues. Also explored for its metabolic stability in vivo, making it a candidate for imaging agents or targeted therapies. Its fluorinated side chain enhances binding specificity and resistance to enzymatic degradation, useful in pharmacokinetic studies.
