Description

Kaempferol 3,4',7-Triacetate is a specific acetylated derivative of the flavonoid kaempferol, a compound of significant interest in biochemical and pharmaceutical research. This derivative is valued for its enhanced stability and altered bioavailability compared to its parent aglycone, making it a crucial intermediate and reference standard. It is primarily sought by research institutions, pharmaceutical developers, and manufacturers of high-purity botanical extracts for applications in drug discovery, metabolic studies, and the development of nutraceutical products.

Application

• Pharmaceutical Research & Development: Serves as a key intermediate in the synthesis of novel flavonoid-based drug candidates and as a reference standard for analytical method development and validation.
• Biochemical Studies: Used to investigate the metabolic pathways, bioavailability, and biological activity of flavonoid compounds in vitro and in vivo.
• Nutraceutical & Cosmetic Ingredient Synthesis: Acts as a precursor or an active ingredient in the formulation of advanced dietary supplements and cosmeceutical products targeting antioxidant and anti-inflammatory benefits.
• Analytical Chemistry: Employed as a high-purity certified reference material (CRM) for the calibration of instruments and quality control in laboratories analyzing flavonoid content.
• Academic Research: Utilized in universities and research institutes for studies on plant biochemistry, natural product chemistry, and structure-activity relationships (SAR).
