Description

Genistin is a major isoflavone glycoside, the 7-O-glucoside of genistein, primarily isolated from soybeans and other legumes. This compound serves as a crucial precursor and standard reference material for the study of phytoestrogens and their bioactive aglycone, genistein. It is essential for research and development in the nutraceutical, pharmaceutical, and food science industries, where precise standardization of isoflavone content is required. Our high-purity Genistin CAS NO 529-59-9 ensures reliable and consistent results for your critical applications.

Application

• Nutraceutical & Dietary Supplement Formulation: Used as a standardized ingredient in soy isoflavone supplements for menopausal and bone health support.
• Pharmaceutical Reference Standard: Serves as a primary chemical reference standard (CRS) for quality control and assay development of genistein-based products.
• Biochemical & Nutritional Research: A key reagent for studying the metabolism, bioavailability, and biological effects of dietary isoflavones in vitro and in vivo.
• Functional Food & Beverage Fortification: Incorporated into foods and drinks to enhance their phytoestrogen content and associated health claims.
• Cosmeceutical Ingredients: Explored for use in topical formulations for its potential antioxidant and skin-conditioning properties.
