Description

R,S Equol 7--D-Glucuronide is a key conjugated metabolite of the soy isoflavone daidzein, specifically the glucuronidated form of the racemic equol. This compound is of significant interest for its role in pharmacokinetic and metabolic studies, providing crucial insights into the bioavailability and excretion pathways of phytoestrogens. It is primarily utilized by research institutions, pharmaceutical developers, and diagnostic manufacturers focused on endocrinology, nutraceutical metabolism, and biomarker analysis.

Application

• Biomedical Research Standard: Serves as a critical reference standard in LC-MS and HPLC assays for quantifying equol metabolites in biological samples (plasma, urine).
• Pharmacokinetic Studies: Used to investigate the absorption, distribution, metabolism, and excretion (ADME) profiles of soy isoflavones and their bioactive derivatives.
• Diagnostic Kit Development: Essential raw material for calibrating immunoassays and enzymatic tests designed to measure phytoestrogen exposure and hormonal activity.
• Nutraceutical & Functional Food Analysis: Employed in quality control laboratories to validate the metabolic fate and efficacy claims of dietary supplements containing daidzein.
• Endocrine Disruptor Research: A vital tool for studying the estrogenic and anti-estrogenic effects of plant-derived compounds in model systems.
