Description

Daidzein 7-β-D-Glucuronide 4’-Sulfate Disodium Salt is a high-purity, water-soluble metabolite of the soy isoflavone daidzein. This compound is of significant interest for its role as a reference standard in analytical research and for investigating the bioavailability and metabolic pathways of dietary isoflavones. It is primarily utilized by research institutions, pharmaceutical developers, and diagnostic manufacturers focused on nutraceutical analysis, pharmacokinetic studies, and biomarker development.

Application

• Analytical Reference Standard: Used as a certified standard for the quantification of daidzein metabolites in biological matrices (e.g., plasma, urine) via HPLC, LC-MS, and LC-MS/MS.
• Pharmacokinetic & Metabolism Research: Essential for studying the absorption, distribution, metabolism, and excretion (ADME) profiles of soy isoflavones in preclinical and clinical research.
• Biomarker Development: Serves as a critical calibrant in developing diagnostic assays to measure isoflavone exposure and metabolic status in nutritional and epidemiological studies.
• Nutraceutical & Functional Food Analysis: Employed to validate the content and metabolic fate of active ingredients in dietary supplements and fortified food products.
• Enzyme Activity Assays: Used as a substrate or reference compound in studies involving sulfotransferase and glucuronidase enzymes.
