Used primarily as a selective estrogen receptor modulator (SERM) in research settings, this compound exhibits high affinity for estrogen receptors and is commonly employed to study estrogenic activity in cellular and molecular assays. It is utilized in the development and testing of pharmaceutical agents targeting hormone-related conditions, such as breast cancer and osteoporosis. Due to its ability to mimic or block estrogen in specific tissues, it serves as a valuable tool in endocrine disruption studies and in the evaluation of receptor-mediated gene expression. Its structural properties also make it useful in the design of fluorescent probes for detecting estrogen receptor presence in biological samples.
