Description

Punicalin CAS NO 65995-64-4 is a bioactive ellagitannin compound, a key polyphenol found in pomegranates and other plants. This high-purity ingredient is valued for its potent antioxidant properties and serves as a critical intermediate in the biosynthesis of other valuable ellagitannins like punicalagin. It is essential for manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries seeking to develop evidence-based products focused on health and wellness. Our supply ensures consistent quality and reliable availability for your research and production needs.

Application

• Nutraceutical & Dietary Supplements: Used as a standardized active ingredient in capsules, tablets, and powders for antioxidant support.
• Pharmaceutical Research: Serves as a reference standard and a key starting material for investigating anti-inflammatory, cardioprotective, and anticancer mechanisms.
• Cosmetic & Skincare Formulations: Incorporated into serums and creams for its protective effects against oxidative stress and environmental skin damage.
• Functional Food & Beverages: Added to health drinks, juices, and fortified foods to enhance their bioactive polyphenol content.
• Analytical & Quality Control: Employed as a high-purity calibration standard in HPLC and LC-MS methods for quantifying ellagitannins in plant extracts and finished products.

Quality Control

Our Punicalin is produced under strict quality management protocols. Each batch is tested to ensure high purity and identity, with typical specifications meeting or exceeding 95% by HPLC. We provide comprehensive Certificates of Analysis (COA) detailing purity, related substances, and residual solvents. Our quality system supports compliance for research, nutraceutical, and cosmetic applications.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep the container tightly sealed under an inert atmosphere such as argon or nitrogen to prevent degradation.
