Description

Pelargonidin-3-o-Rutinoside Chloride(Rg) is a specific anthocyanin derivative, a natural pigment belonging to the flavonoid class of polyphenolic compounds. This high-purity standard is critical for research and development, providing a reliable reference for analytical and biological studies. It is primarily sought by professionals in the nutraceutical, cosmetic, and analytical chemistry industries for its role in standardization, quality control, and as a key ingredient in natural colorant and antioxidant formulations.

Application

• Analytical Reference Standard: Used as a primary standard in HPLC, LC-MS, and other chromatographic methods for the identification and quantification of anthocyanins in complex matrices like plant extracts, foods, and beverages.
• Nutraceutical & Functional Food Ingredient: Incorporated into dietary supplements and fortified foods for its potential antioxidant properties and as a natural colorant.
• Cosmetic & Personal Care Formulations: Utilized in skincare products for its antioxidant activity and as a natural pigment in color cosmetics.
• Biochemical & Pharmaceutical Research: Serves as a key reagent in studying the bioavailability, metabolism, and potential health benefits of anthocyanins and related polyphenols.
• Natural Food Colorant Development: Acts as a model compound for developing stable, natural red-to-purple colorants for the food and beverage industry.
• Plant Extract Standardization: Essential for standardizing anthocyanin-rich botanical extracts (e.g., from berries, grapes, purple sweet potatoes) to ensure consistent potency and efficacy.

Quality Control

Our Pelargonidin-3-o-Rutinoside Chloride(Rg) is manufactured under strict quality protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV-Vis), to ensure it meets high-grade specifications suitable for research and development. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label or COA. Due to its hygroscopic nature, the container should be kept sealed in a desiccated environment to prevent moisture absorption.
