Description

3,3',4',5,5',7,8-Heptamethoxyflavone is a highly substituted polymethoxyflavone (PMF), a significant subclass of flavonoid compounds. This compound is valued for its role as a key analytical reference standard and a promising bioactive molecule in research and development. It is primarily sought by the pharmaceutical, nutraceutical, and advanced chemical synthesis sectors for applications in quality control, metabolic studies, and the development of novel therapeutic agents.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and purity testing of flavonoid-based drugs and herbal extracts in QC/QA laboratories.
• Nutraceutical & Dietary Supplement Research: Serves as a standard compound in the study of bioavailability, metabolism, and standardization of citrus-based or polymethoxyflavone-rich supplements.
• Biochemical & Pharmacological Research: Investigated for its potential biological activities, including anti-inflammatory, antioxidant, and anti-cancer properties in preclinical studies.
• Chemical Synthesis Intermediate: Acts as a sophisticated building block or precursor for the semi-synthesis of novel flavonoid derivatives with tailored properties.
• Analytical Method Development: Employed as a calibration standard in HPLC, LC-MS, and other chromatographic methods for quantifying PMFs in complex matrices.
• Cosmeceutical Ingredient Research: Studied for potential application in advanced skincare formulations due to the bioactive profile characteristic of flavonoids.
