Description

Caftaric Acid is a hydroxycinnamic acid derivative and a key phenolic compound naturally found in grapes and wine. It serves as a crucial marker for authenticity and quality in the food and beverage industry, offering potent antioxidant properties. This compound is essential for manufacturers and researchers in the nutraceutical, cosmetic, and analytical chemistry sectors seeking high-purity natural antioxidants and reference standards.

Application

• Wine & Beverage Analysis: Used as a primary reference standard for HPLC analysis to quantify phenolic content, assess authenticity, and monitor oxidation processes in wines, juices, and other plant-based beverages.
• Nutraceutical & Dietary Supplements: Incorporated into formulations for its strong antioxidant activity, helping to neutralize free radicals and support cellular health.
• Cosmetic & Skincare Products: Utilized as a natural active ingredient in anti-aging and protective creams and serums due to its ability to combat oxidative stress caused by UV exposure.
• Pharmaceutical Research: Serves as a biochemical intermediate and a compound of interest in studies investigating anti-inflammatory, cardioprotective, and neuroprotective effects.
• Food Science & Quality Control: Acts as a benchmark for evaluating the phenolic profile, shelf-life stability, and overall quality of fruits, vegetables, and their processed products.
• Botanical Extract Standardization: Employed to standardize and authenticate grape seed extract, green tea extract, and other herbal products rich in caffeoyl derivatives.

Quality Control

Our Caftaric Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV), to ensure it meets high-grade specifications suitable for analytical and research applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain stability and potency. For long-term storage, consider an inert atmosphere.
