The Uses of DL-ALPHA-TOCOPHEROL ACETATE
dl-α-Tocopherol Acetate is the racemic analog of α-Tocopherol Acetate (T526155), one of the most bioactive of the naturally occurring forms of Vitamin E. Richest sources are green vegetables, grains, and oils, particularly palm, safflower and sunflower oils.
The Uses of DL-ALPHA-TOCOPHEROL ACETATE
This internal standard is suitable for HPLC or LC-MS/MS Vitamin E testing applications such as quality control testing of Vitamin E fortified foods, dietary supplements, or pharmaceuticals.
Tocopheryl Acetate (Vitamin E acetate) may be used as an analytical standard for the determination of the analyte in aquatic organisms, fish feed and pharmaceutical formulations by colorimetric and chromatography techniques, respectively.
Definition
ChEBI: Alpha-Tocopherol acetate is a tocol.
General Description
Tocopheryl acetate is a natural form of Vitamin E, used as a fortifying agent and dietary supplement for Vitamin E in food. It is also the main ingredient of skin care products and dermatological preparations. Tocopheryl acetate in combination with α-tocopherol has been used in the therapy of conditions such as sterility, muscular dystrophy, cardiac vascular disorders and anemia.
