Description

D-α-Tocopherol Succinate CAS NO 4345-03-3 is a high-purity, fat-soluble ester derivative of natural vitamin E (D-α-tocopherol). This compound is valued for its enhanced stability and bioavailability compared to the free tocopherol form, making it a critical ingredient for premium nutritional and pharmaceutical formulations. It is primarily required by manufacturers in the nutraceutical, pharmaceutical, and high-end cosmetic industries seeking a reliable, high-quality source of vitamin E activity.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in softgel capsules, tablets, and liquid formulations for antioxidant support.
• Pharmaceutical Formulations: Used in injectable and oral dosage forms as a stabilizer and active pharmaceutical ingredient (API) for vitamin E therapy.
• Cosmetics & Personal Care: Incorporated into anti-aging serums, creams, and lotions for its skin-conditioning and antioxidant properties.
• Functional Food & Beverage Fortification: Employed to enrich foods and drinks with stable vitamin E, often where oil solubility is required.
• Animal Nutrition (Premix): Used in vitamin premixes for livestock, poultry, and pet food to ensure adequate vitamin E levels.
• Research & Development: Serves as a standard or reagent in biochemical and nutritional studies.
