Description

p-Coumaric acid (CAS 7400-08-0 ), also recognized commercially as p-hydroxycinnamic acid, is a naturally occurring hydroxycinnamic acid sourced from plant extracts or produced synthetically for industrial supply. It functions primarily as an antioxidant, UV-absorbing agent, and bioactive intermediate across pharmaceutical, nutraceutical, and cosmetic manufacturing. In pharmaceutical synthesis, it serves as a key intermediate. This material is used in the production of active compounds, including resveratrol analogs and other polyphenolic APIs. Nutraceutical and functional food formulators incorporate it as a plant-derived antioxidant. It is frequently found in dietary supplements, botanical extracts, and standardized herbal preparations. In cosmetic formulations, its UV-absorbing and antioxidant properties make it relevant for inclusion. Common applications include sunscreen actives, anti-aging serums, and skin-brightening products. Food manufacturers also evaluate it as a natural antioxidant stabilizer in specialty food and beverage applications. The product is supplied as an off-white to pale yellow crystalline powder. It is available in technical grade for industrial synthesis and in higher-purity grades for specialized manufacturing. These include USP -aligned and research-grade specifications for pharmaceutical and nutraceutical applications. Packaging typically ranges from small quantities for development to bulk quantities. Our supply chain ensures consistent quality for commercial-scale production. We provide comprehensive documentation to support regulatory compliance and formulation stability across all industrial sectors. Contact us for supply of p-coumaric acid Request Quote
