Dark red crystalline powder. No odor, no taste, sensitive to light. It is hygroscopic and absorbs 12% of water in the air. Its hydrous crystals are stable in air. When the temperature is 210 to 220 ° C, the color becomes dark, and 300 ° C does not melt. The aqueous solution is neutral and most stable at pH 4.5 to 5. 1 g is dissolved in about 80 ml of water, soluble in ethanol, and insoluble in acetone, chloroform and diethyl ether. Specific optical rotation -59 ° ± 9 ° (deep aqueous solution). Maximum absorption wavelength (in water) 278, 361, 550 nm (A1% 1 cm 115, 204, 64). Minimum lethal dose (rat, abdominal cavity) 1364mg/kg.
