Description

Cyanidin 3-o-Rutinoside 5-o-β-D-Glucoside is a specific anthocyanin, a class of water-soluble pigments responsible for the vibrant red, purple, and blue colors in many fruits and vegetables. This compound is valued for its potent antioxidant properties and its role as a key analytical standard and bioactive ingredient. It is primarily sought by manufacturers and researchers in the nutraceutical, food & beverage, cosmetic, and analytical chemistry sectors for product development, quality control, and scientific studies.

Application

• Nutraceutical & Dietary Supplement Formulation: Used as a key bioactive ingredient in antioxidant supplements and health products targeting cellular health and inflammation.
• Natural Food & Beverage Coloring: Serves as a high-value, clean-label colorant for beverages, confectionery, yogurts, and other food products.
• Cosmetic & Skincare Products: Incorporated into serums and creams for its antioxidant and potential skin-protective benefits against environmental stressors.
• Pharmaceutical Research: Investigated for its potential therapeutic effects in preclinical studies related to metabolic and inflammatory conditions.
• Analytical Reference Standard: Essential for HPLC and LC-MS analysis to quantify anthocyanin content in botanical extracts, finished products, and for method validation.
• Botanical Extract Standardization: Used to standardize and enhance the potency of berry extracts (e.g., elderberry, blackcurrant) and other anthocyanin-rich raw materials.
