【Physical and chemical properties】

Off-white fine powder. It is easy to oxidize to yellow when exposed to sunlight and air. Soluble in benzene and chloroform. 1g of the product is soluble in 660ml of cold ethanol, 45ml of boiling ethanol, 70ml of cold ether, 39ml of boiling ether, 31ml of chloroform, almost insoluble in water. Can be precipitated by digitonin. Specific optical rotation [α]D-135° (chloroform, C=1.2). Maximum absorption wavelengths (in ethanol) 262, 271, 282, 293 nm. Ergosterol is irradiated by ultraviolet rays and undergoes a series of changes to produce vitamin D2; 22,23-dihydroergosterol, a derivative of ergosterol, is converted to vitamin D4 after exposure to ultraviolet light. Used in biochemical research. It has the effect of vitamin D2. Specific rotation -135° (C=1.2, chloroform)
