Description

D-α-Tocopherylquinone is a key oxidized metabolite and synthetic intermediate of Vitamin E (α-tocopherol). This compound matters for its critical role in biochemical research and as a precursor in the synthesis of high-purity tocopherols and tocotrienols. It is needed by manufacturers in the pharmaceutical, nutraceutical, and fine chemical industries for developing antioxidant formulations and reference standards.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of high-purity D-α-tocopherol (natural Vitamin E) and its derivatives.
• Biochemical Research: Used as a reference standard and reagent in studies of Vitamin E metabolism, antioxidant mechanisms, and oxidative stress.
• Nutraceutical Production: Serves as a starting material for the manufacture of premium-grade Vitamin E supplements and fortified foods.
• Cosmetic Ingredients: Employed in the synthesis of tocopheryl acetate and other Vitamin E esters for skin care and anti-aging formulations.
• Analytical Chemistry: Acts as a calibration standard in HPLC and GC analyses for quantifying tocopherols in various matrices.
• Food Science: Utilized in research on lipid oxidation and the development of natural preservative systems.
