Description: Biochemical research; Medically used for vitamin E deficiency; Antioxidant and catalytic hydrogenation agent in vegetable oil.
Level: AR
Content: ≥98.0%
Properties: Light yellow or brown oily or slightly viscous liquid, almost odorless. Melting point 2.5-3.5℃, boiling point 200-220℃ (13 pa), relative density (25/4℃) 0.950, refractive index 1.5045. Fat soluble, soluble in alcohol, ether, acetone, chloroform, fat and other fat solvents, almost insoluble in water. When there is no oxygen, it is very stable to the hot alkali, and has no effect on the acid below 100 ° C, but it is easy to be oxidized, and the color gradient is dark in the light, and the presence of iron salt and silver salt can accelerate its oxidation. It can be oxidized to quinone derivatives in the air by light or chemical reagents. It is found in vegetable oils, such as wheat germ, corn, sunflower seed, rapeseed and soybean oil, and often coexists with β-type and γ-type
Storage: -20℃, away from light
