Caffeic acid

Caffeic acid (CAS 331-39-5 ), also known as 3,4-Dihydroxycinnamic Acid, is a hydroxycinnamic acid naturally occurring in many plants and widely sourced for use across pharmaceutical, nutraceutical, and cosmetic manufacturing. It functions primarily as an antioxidant and UV-stabilizing agent in finished formulations. In pharmaceutical manufacturing, it serves as an intermediate in the synthesis of active compounds and is incorporated into antioxidant-focused dietary supplement formulations. Food and beverage producers use it as a natural antioxidant to extend shelf life and protect against oxidative degradation in sensitive products. In personal care and cosmetic formulations, it is valued for its UV-stabilizing properties. This makes it a candidate ingredient in sunscreen boosters and anti-aging topical products. Nutraceutical formulators also include it in standardized botanical extracts where polyphenol content is a defined quality parameter. The product is supplied as a fine crystalline powder, typically off-white to light beige in color. It is available in technical and pharmaceutical-grade specifications to meet the requirements of different regulatory environments. Purity levels of 98% and above are standard for pharmaceutical and nutraceutical applications. Documentation such as COA and HPLC testing is commonly provided to ensure compliance with global industry benchmarks. Contact us for supply of Caffeic acid Request Quote
