Kaempferol 3,4'-diglucoside 7-rhamnoside 98% Purity Natural Product Reference Standard CAS 1131009-93-2 Research Grade Flavonoid Triglycoside

• Product Overview

  Kaempferol 3,4'-diglucoside 7-rhamnoside is a naturally occurring flavonoid triglycoside featuring the flavonol aglycone kaempferol with three sugar moieties attached at three distinct positions: β-D-glucopyranosyl at the 3-position, β-D-glucopyranosyl at the 4'-position, and α-L-rhamnopyranosyl at the 7-position. This complex glycosylation pattern confers unique physicochemical properties and enhanced water solubility compared to less glycosylated flavonols. With a molecular formula approximately C₃₃H₄₀O₂₀ and a molecular weight of approximately 756.67 g/mol, this compound appears as a light yellow powder. It serves as a valuable reference standard for phytochemical analysis and flavonoid research.
