Description

5-Hydroxy-7-Acetoxyflavone is a specific flavonoid derivative characterized by its acetylated hydroxy group at the 7-position. This structural modification makes it a valuable intermediate and reference standard for research into the synthesis, metabolism, and bioactivity of natural flavonoids. It is primarily sought after by research institutions and manufacturers in the life sciences sector for its role in phytochemical studies and as a potential precursor for novel compounds. The compound is supplied to meet the stringent requirements of analytical and synthetic chemistry applications.

Application

• Phytochemical Reference Standard: Used as a high-purity analytical standard in HPLC and LC-MS for the identification and quantification of flavonoids in plant extracts and herbal products.
• Biochemical Research: Serves as a key intermediate or substrate in studies investigating flavonoid metabolism, enzyme inhibition, and structure-activity relationships (SAR).
• Pharmaceutical Intermediates: Acts as a building block for the semi-synthesis of more complex flavonoid analogs with potential therapeutic applications.
• Nutraceutical & Cosmeceutical R&D: Employed in research to develop new ingredients with antioxidant, anti-inflammatory, or UV-protective properties for dietary supplements and skincare formulations.
• Academic Research: Utilized in university and institutional labs for chemical education and fundamental research on natural product chemistry.
