Description

Kaempferol 3-Robinoside 7-Glucoside is a specific flavonoid glycoside, a natural polyphenolic compound derived from plants. This high-purity reference standard is critical for analytical research, quality control, and the development of standardized botanical extracts. It serves as an essential material for researchers and manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries who require precise identification and quantification of bioactive flavonoid components.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and purity testing of kaempferol glycosides in drug substances and herbal medicinal products.
• Nutraceutical & Dietary Supplement Analysis: Acts as a quantitative marker in the standardization of botanical extracts (e.g., from ginkgo, propolis, or various fruits) for consistent bioactive content.
• Academic & Biomedical Research: Employed in in vitro and in vivo studies to investigate the antioxidant, anti-inflammatory, and potential chemopreventive properties of flavonoid compounds.
• Cosmetic Ingredient Standardization: Used to standardize and verify the potency of plant-derived active ingredients in skincare formulations targeting oxidative stress.
• Food & Beverage Quality Control: Serves as an analytical standard for quantifying flavonoid content in functional foods, beverages, and for authenticity testing.
• Method Development & Validation: Essential for developing and validating analytical methods (HPLC, LC-MS) for flavonoid profiling in complex matrices.

Quality Control

Our Kaempferol 3-Robinoside 7-Glucoside is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, MS), to ensure it meets the high standards required for research and analytical applications. A detailed Certificate of Analysis (COA) documenting purity, identity, and relevant specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants.
