Description

Isoscutellarein 8-o-Glucuronide is a specific flavonoid glucuronide, a key metabolite and bioactive compound derived from natural sources. This high-purity reference standard is critical for analytical research, method development, and quality control in the pharmaceutical and nutraceutical industries. It is primarily sought by researchers and quality assurance professionals in phytochemistry, pharmacology, and analytical laboratories for its role in standardization and bioactivity studies.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quantitative and qualitative analysis of herbal extracts and finished products.
• Metabolite Research: Serves as a critical standard in pharmacokinetic and metabolic studies to track the absorption and distribution of flavonoid compounds.
• Bioactivity Screening: Employed in in vitro and in vivo studies to investigate potential anti-inflammatory, antioxidant, or other therapeutic properties.
• Quality Control (QC) in Nutraceuticals: Essential for the assay and identification testing of dietary supplements containing Scutellaria or related botanicals to ensure label claim and potency.
• Method Development & Validation: A key component in developing and validating robust analytical methods, particularly High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS) protocols.
