Used primarily in research settings as a selective estrogen receptor modulator (SERM) antagonist. It is especially valuable in studies involving estrogen signaling pathways due to its ability to block estrogen receptor activity with high specificity. Commonly employed in cellular and molecular biology experiments to investigate hormone-dependent processes, including those in breast cancer models. Its modified steroid structure enhances stability and receptor binding affinity, making it suitable for probing receptor function and for use in developing hormone-based therapeutics. Also utilized in reproductive biology research to modulate estrogenic effects in experimental systems.
