Delphinidin-3-rhamnoside chloride 98% Purity Natural Product Reference Standard CAS 29907-19-5 Research Grade Anthocyanin

• • • Product Overview

      Delphinidin-3-rhamnoside chloride is a naturally occurring anthocyanin pigment, consisting of the delphinidin aglycone glycosylated with an α-L-rhamnopyranosyl moiety at the 3-position, with chloride as the counterion. Delphinidin is a member of the anthocyanidin class, characterized by its distinctive blue to purple-red color due to the presence of multiple hydroxyl groups on the B-ring. This compound exhibits characteristic UV-Vis absorption maxima at approximately 540 nm, making it easily identifiable and quantifiable by spectroscopic methods. With a molecular formula approximately C₂₁H₂₁ClO₁₁ and a molecular weight of approximately 484.84 g/mol, this compound appears as a dark red to purple-red powder. It serves as a valuable reference standard for anthocyanin analysis in food, pharmaceutical, and natural product research.

      Natural Sources

      Delphinidin-3-rhamnoside is found in various pigmented plant tissues, including berries, flowers, and purple-colored fruits. It is responsible for the blue, violet, and purple colors observed in many plant species and is often accompanied by other anthocyanins such as cyanidin and malvidin derivatives.
