Description

Cyanidin 3-o-2G-Glucosylrutinoside is a specific, complex anthocyanin pigment, a subclass of polyphenolic flavonoids. This compound matters for its potent antioxidant properties and its role as a natural colorant, offering a stable and vibrant hue. It is primarily needed by manufacturers in the nutraceutical, functional food, and cosmetic industries seeking natural bioactive ingredients. Our supply ensures high purity and batch-to-batch consistency for demanding B2B applications.

Application

• Natural Food & Beverage Colorant: Used to impart stable red, purple, or blue shades to drinks, confectionery, dairy products, and fruit preparations.
• Dietary Supplement Formulation: Incorporated into capsules, tablets, and powders for its well-documented antioxidant and anti-inflammatory bioactivity.
• Functional Food Enhancement: Added to health-focused products like cereal bars and yogurts to boost their polyphenol content and associated health claims.
• Cosmetic & Personal Care: Utilized in skincare formulations for its antioxidant properties, helping to protect the skin from environmental stressors.
• Pharmaceutical Research: Serves as a reference standard or active pharmaceutical ingredient (API) intermediate in clinical and preclinical studies.
• Analytical Standard: Employed in laboratories as a high-purity calibration standard for HPLC, LC-MS, or other analytical methods quantifying anthocyanins.

Quality Control

Our Cyanidin 3-o-2G-Glucosylrutinoside is produced and tested under strict quality management systems. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and composition. A comprehensive Certificate of Analysis (COA) detailing HPLC assay, related substance profiles, and residual solvent analysis is provided with every shipment. We support compliance with relevant standards for nutraceutical and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. For daily use, store desiccated at 2-8°C. This material is easily oxidized; keep container tightly sealed under an inert atmosphere (e.g., nitrogen) when possible and minimize headspace. Handle in a controlled environment to limit exposure to heat, light, and moisture.
