Isorhamnetin 3-O-glucoside

Isorhamnetin 3-O-glucoside (CAS 5041-82-7), also referred to commercially as isorhamnetin-3-Glu, is a naturally occurring flavonoid glycoside isolated primarily from plant sources such as sea buckthorn and onion.

It functions as a bioactive antioxidant ingredient in nutraceutical, pharmaceutical, and research-grade formulations. In dietary supplement manufacturing, it is incorporated into capsule and tablet formulations.

These applications target antioxidant and cardiovascular health positioning. Pharmaceutical and nutraceutical developers use it as a reference standard or active botanical ingredient in standardized plant extracts.

Biotechnology and life sciences laboratories source it as an analytical reference compound for HPLC method development, metabolite profiling, and in vitro bioactivity screening for various research projects.

Food and functional beverage formulators apply it in products where polyphenol content is a measurable quality or marketing parameter. It is supplied as a fine powder, typically at purity levels of 95% or 98%.

Purity is confirmed by HPLC, and it is available in research quantities for laboratory use and in larger batch sizes for industrial or clinical supply. Both standard-grade and high-purity reference-grade material are offered.
