Description

3,4-Dihydro-2,7,8-Trimethyl-3-(4,8,12-Trimethyltridecyl)-2H-1-Benzopyran-6-Yl Hexadecanoate is a high-purity synthetic ester derivative of a tocol, specifically a palmitate ester of a trimethyltocopherol isomer. This compound is valued for its potent antioxidant properties and stability, making it a critical intermediate and functional additive in advanced formulations. It is primarily sought by manufacturers in the nutraceutical, cosmetic, and specialty chemical industries for developing high-performance products requiring enhanced oxidative stability.

Application

• Nutraceutical & Dietary Supplement Formulations: Used as a stabilized, oil-soluble antioxidant ingredient in softgel capsules and liquid supplements.
• Cosmetic & Personal Care Actives: Incorporated into anti-aging serums, creams, and lotions for its skin-conditioning and protective benefits against environmental stressors.
• Functional Food & Beverage Fortification: Serves as a lipid-soluble antioxidant additive to enhance the shelf-life and nutritional profile of oils and fat-based food products.
• Pharmaceutical Intermediates: Acts as a key synthetic precursor in the production of specialized tocopherol and tocotrienol derivatives.
• Animal Feed Additives: Utilized in premium feed formulations to improve the oxidative stability of fat-soluble vitamins and nutrients.
• Industrial Antioxidants: Employed as a stabilizer in lubricants, polymers, and other industrial materials susceptible to degradation.
