Description

Kaempferol CAS NO 520-18-3 is a naturally occurring flavonol, a subclass of flavonoids, recognized for its potent biological activities. This high-purity phytochemical is essential for research and development in the nutraceutical, pharmaceutical, and cosmetic industries, where its antioxidant and anti-inflammatory properties are highly valued. It serves as a critical reference standard, active pharmaceutical ingredient (API) intermediate, and a key functional component in dietary supplements and advanced skincare formulations.

Application

• Pharmaceutical Research & Development: Used as a reference standard for analytical methods (HPLC, LC-MS) and as a lead compound in drug discovery for its anti-inflammatory, anticancer, and cardioprotective properties.
• Nutraceutical & Dietary Supplements: Incorporated into formulations for antioxidant support, promoting cellular health and combating oxidative stress.
• Cosmetics & Personal Care: Valued in anti-aging and protective skincare products for its ability to neutralize free radicals and support skin barrier function.
• Food & Beverage Fortification: Acts as a natural antioxidant additive to enhance the shelf-life and nutritional profile of functional foods and beverages.
• Biochemical & Life Science Research: A vital tool for studying flavonoid metabolism, signal transduction pathways, and cellular mechanisms in vitro and in vivo.
• Agricultural & Animal Health: Investigated for use in animal feed additives and plant growth regulators due to its bioactive properties.

Quality Control

Our Kaempferol is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, identity confirmation via IR and UV spectroscopy, and residual solvent analysis to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) detailing all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, prolonged exposure to light, air, or elevated temperatures should be avoided. For long-term storage, consider an inert atmosphere.
