Description

Myricetin 3-o-Glucuronide is a specific flavonoid glucuronide, a key metabolite of the bioactive flavonol myricetin. This compound matters for researchers and formulators seeking to understand and utilize the bioavailability and metabolic pathways of natural polyphenols. It is primarily needed by the pharmaceutical, nutraceutical, and life science research industries for applications in metabolic studies, reference standards, and the development of standardized botanical extracts.

Application

• Pharmaceutical Reference Standard: Used as a high-purity certified reference material (CRM) for analytical method development and validation in drug discovery and pharmacokinetic studies.
• Nutraceutical & Dietary Supplement Research: Serves as a critical marker compound for the standardization and quality control of myricetin-containing botanical extracts, such as those from bayberry, grapes, or tea.
• Metabolite & Bioavailability Studies: Essential for in vitro and in vivo research investigating the absorption, distribution, metabolism, and excretion (ADME) of myricetin and related flavonoids.
• Biochemical Research Reagent: Employed in enzymatic assays and studies on glucuronidation pathways and phase II metabolism.
• Cosmeceutical Ingredient Research: Investigated for potential topical applications due to the antioxidant properties inherent to the myricetin moiety.
