Kaempferol 3-robinoside 7-glucoside 98% Purity Natural Product Reference Standard CAS 114924-89-9 Research Grade Flavonoid Diglycoside

• • Product Overview

    Kaempferol 3-robinoside 7-glucoside is a naturally occurring flavonoid diglycoside featuring the flavonol aglycone kaempferol with a robinobiosyl moiety at the 3-position and a β-D-glucopyranosyl moiety at the 7-position. The robinobiose is a disaccharide composed of α-L-rhamnose and β-D-galactose linked through a (1→6) glycosidic bond. This compound exhibits the characteristic UV absorption of flavonols with maxima at approximately 266 nm and 348 nm. With a molecular formula approximately C₃₃H₄₀O₂₀ and a molecular weight of approximately 756.67 g/mol, this compound appears as a light yellow powder and serves as a valuable reference standard for phytochemical analysis.
