Description

Oenin Chloride is a specific anthocyanin compound, a key pigment responsible for the red and blue hues in many plants and fruits. This high-purity standard is essential for research, analytical applications, and product development where precise chemical identity and consistent quality are paramount. It is particularly valuable for laboratories in the nutraceutical, food science, and analytical chemistry sectors requiring a reliable reference material for quantification and method validation. Its stability and defined properties make it a critical component for studies on natural colorants and antioxidants.

Application

• Analytical Reference Standard: Used as a primary standard in High-Performance Liquid Chromatography (HPLC) and other analytical methods for the quantification of anthocyanins in complex matrices like wines, fruit juices, and botanical extracts.
• Nutraceutical & Dietary Supplement Research: Serves as a key material in studies investigating the bioavailability, metabolism, and potential health benefits of specific anthocyanin compounds.
• Food & Beverage Colorant Analysis: Employed in quality control laboratories to authenticate and quantify natural colorant content, ensuring product consistency and compliance with labeling regulations.
• Phytochemical and Botanical Standardization: Acts as a marker compound for the standardization of grape skin, bilberry, elderberry, and other anthocyanin-rich herbal extracts.
• Biochemical Research: Utilized in in vitro studies to explore mechanisms of action related to antioxidant capacity, enzyme inhibition, and cellular signaling pathways.
• Cosmetic Ingredient Research: Investigated for its potential stabilizing and coloring properties in formulations where natural, plant-derived ingredients are desired.
