Description

Kaempferol 3,4‘-Diglucoside 7-Rhamnoside is a specific flavonol glycoside, a naturally occurring polyphenolic compound derived from plants. This high-purity reference standard is critical for analytical research, quality control, and the development of nutraceutical and pharmaceutical products. It is primarily utilized by researchers and manufacturers in the phytochemical, pharmaceutical, and dietary supplement industries who require a reliable and well-characterized compound for method validation and product standardization.

Application

• Phytochemical Reference Standard: Used as a certified reference material (CRM) for the identification and quantification of kaempferol derivatives in plant extracts and botanical products via HPLC, LC-MS, and other analytical techniques.
• Pharmaceutical Research: Serves as a key intermediate or active pharmaceutical ingredient (API) precursor in studies investigating the anti-inflammatory, antioxidant, and potential anticancer properties of flavonoid compounds.
• Nutraceutical & Dietary Supplement Formulation: Employed in the standardization of complex botanical extracts to ensure consistent potency and efficacy in finished health products.
• Food & Beverage Analysis: Acts as an analytical marker for quality control and authenticity verification in products containing flavonoid-rich ingredients like tea, fruits, and vegetables.
• Cosmeceutical Development: Incorporated into research for skincare formulations leveraging the antioxidant and UV-protective properties of flavonoids.
• Academic & Biochemical Research: Utilized in university and institutional labs for studying flavonoid metabolism, biosynthesis pathways, and structure-activity relationships (SAR).
