Used primarily in the development of pharmaceutical formulations for hormone therapy, particularly in treatments related to estrogen modulation. Its structure allows for high receptor binding affinity, making it effective in managing conditions such as breast cancer, menopausal symptoms, and certain gynecological disorders. It is also employed in research settings to study estrogen receptor activity and signaling pathways. Due to its selective action, it contributes to therapies aiming to minimize systemic hormonal side effects.
