Physicochemical properties: light yellow or slightly green needle crystal or powder. Odorless. Tasteless. The color becomes darker under the action of light. It usually contains 3 molecules of crystal water. After drying at 95 ~ 97 ℃ and losing 2 molecules of crystal water, it becomes anhydrous after 12 hours under 110 ℃ and 1.33kpa pressure, becomes Brown at 125 ℃, becomes flexible and plastic at 195 ~ 197 ℃, decomposes and bubbles at 214 ~ 215 ℃. Anhydrous substances are easy to absorb moisture. 1g is soluble in about 8L water, about 200ml boiling water and 7ml boiling methanol. It is soluble in pyridine, formamide and lye, slightly soluble in ethanol, acetone and ethyl acetate, and almost insoluble in chloroform, benzene, carbon disulfide and petroleum solvents. The dilute solution is green when it meets with ferric oxide. Specific rotation[ α] 23d+13.82 ° (in ethanol)..

Purpose: biochemical research. An inhibitor of lens aldose reductase. It is also used as food antioxidant and pigment

Save: RT, away from light
