Description

Daidzin CAS NO 552-66-9 is a major isoflavone glycoside, a natural bioactive compound primarily extracted from legumes such as soybeans and kudzu root. This compound is of significant commercial interest due to its role as a precursor to the more potent metabolite daidzein, which is associated with various health-promoting properties. It is a critical raw material for manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries, where it is utilized for its antioxidant and phytoestrogenic activities.

Application

• Nutraceutical & Dietary Supplements: A key ingredient in formulations targeting women's health, bone support, and antioxidant defense systems.
• Pharmaceutical Intermediates: Serves as a starting material or reference standard in the research and development of drugs related to hormonal balance and metabolic disorders.
• Cosmetic & Skincare Products: Incorporated into anti-aging and skin-rejuvenating creams and serums for its antioxidant and potential collagen-stimulating effects.
• Functional Food & Beverage Fortification: Used to enhance the nutritional profile of health-focused foods and drinks with plant-based bioactive compounds.
• Research & Development: Employed as a high-purity biochemical reagent in academic and industrial laboratories studying isoflavone metabolism, bioavailability, and bioactivity.
• Veterinary Supplements: Applied in animal health products designed to support overall wellness and specific physiological functions.
