Used in pharmaceutical, biochemical, and pharmacological research for its potential estrogenic and antioxidant properties. It exhibits estrogen-like activity and is studied for its role in hormone-related therapies, including alleviation of menopausal symptoms such as hot flashes and osteoporosis. Investigated for anticancer activity, particularly in breast and prostate cancers, and potential prevention of heart disease due to its interaction with estrogen receptors. Also explored for metabolic health benefits, including glucose regulation and lipid metabolism. Commonly used as a standard in analyzing plant extracts, especially from soy and fermented soy products, to quantify bioactive isoflavonoids. Additionally, employed in in vitro and animal models to evaluate bioavailability and biological activity of isoflavone derivatives.
