Description

(+/-)-Enterodiol CAS NO 77756-22-0 is a mammalian lignan metabolite, a key compound formed by the gut microbiota from dietary precursors found in seeds, grains, and berries. Its significance lies in its role as a biomarker for dietary lignan intake and a subject of research for its potential bioactive properties. This high-purity reference standard is essential for researchers and quality control laboratories in the nutraceutical, pharmaceutical, and life science sectors, supporting analytical method development, metabolic studies, and product formulation.

Application

• Analytical Reference Standard: For use in HPLC, LC-MS, and GC-MS methods to quantify enterodiol levels in biological samples, foods, and dietary supplements.
• Nutraceutical & Functional Food Research: As a key ingredient or marker in studies investigating the health benefits of phytoestrogens and dietary lignans.
• Biomarker Studies: Utilized in clinical and nutritional research to correlate lignan intake with health outcomes by measuring its metabolite concentration.
• Pharmaceutical Development: Serves as a starting material or intermediate in the research of novel therapeutics targeting hormonal or metabolic pathways.
• Microbiome & Metabolism Research: Used to study the bioconversion of plant lignans by intestinal bacteria and subsequent pharmacokinetics.
• Quality Control (QC) & Assurance: Acts as a primary standard for the assay and purity testing of lignan-containing raw materials and finished products.
