Chemische Eigenschaften
off-white crystalline solid
Verwenden
(+)-α-Tocopherol acetate has been used:
- as a component of growth medium for retinal cell lines
- as an external standard in high performance liquid chromatography (HPLC) to study its composition in leafy vegetables
- in the preparation of trans-resveratrol-encapsulated lipid nanocarriers (R-nano)
Verwenden
α-Tocopherol acetate is 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.
Verwenden
Used in prevention and treatment of vitamin E deficiencies.
Definition
ChEBI: Alpha-Tocopherol acetate is a tocol.
Allgemeine Beschreibung
Odorless off-white crystals. Darkens at 401° F.
Air & Water Reaktionen
D-alpha-Tocopheryl acetate may be sensitive to prolonged exposure to light and air. . Insoluble in water.
Reaktivität anzeigen
An ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Brandgefahr
Flash point data for D-alpha-Tocopheryl acetate are not available. D-alpha-Tocopheryl acetate is probably combustible.
Kontakt-Allergie
Tocopherol and tocopheryl acetate are used mainly as antioxidants. Tocopheryl acetate, an ester of tocopherol (vitamin E), can induce allergic contact dermatitis.
Biochem/physiol Actions
α-Tocopherol acetate or vitamin E-acetate has antioxidant properties and reduces lipid peroxidation. However, vitamin E acetate on pyrolysis leads to the generation of carcinogens like alkenes and benzenes.
Sicherheitsprofil
When heated to decomposition it emits acrid smoke and irritating fumes.
