Description

Petunidin 3-Glucoside is a naturally occurring anthocyanin, a specific type of flavonoid pigment responsible for vibrant colors in many fruits and flowers. This compound is valued for its potent antioxidant properties and its role as a stable colorant. It is primarily sought after by manufacturers in the nutraceutical, cosmetic, and food & beverage industries for applications ranging from natural colorants to functional ingredient formulations.

Application

• Natural Food & Beverage Colorant: Used to impart stable red, purple, and blue hues to drinks, confectionery, dairy products, and functional foods.
• Nutraceutical & Dietary Supplements: Incorporated into capsules, tablets, and powders for its well-documented antioxidant and potential health-promoting benefits.
• Cosmetic & Personal Care Formulations: Serves as a natural color additive and active ingredient in skincare products for its antioxidant and skin-protective properties.
• Pharmaceutical Research: Utilized as a reference standard or active pharmaceutical ingredient (API) intermediate in research and development.
• Analytical & Laboratory Use: Employed as a high-purity standard for HPLC, LC-MS, and other analytical methods in quality control and research laboratories.
• Plant & Agricultural Biochemistry Studies: Used in research to study plant pigmentation, flavonoid biosynthesis, and related metabolic pathways.

Quality Control

Our Petunidin 3-Glucoside is produced and tested under strict quality management systems. Each batch is analyzed to ensure high purity and consistency, with specifications tailored to meet the requirements of food, cosmetic, and nutraceutical applications. Comprehensive testing includes identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under inert atmosphere when possible and opened in a controlled, low-humidity environment.
