NH4[Cr(NH3)2(SCN)4]=336.43

Grade: ar

Water dissolution test: acceptable

Sensitivity test for choline chloride: acceptable

 Physicochemical Properties: dark red crystal or red crystalline powder. Soluble in hot water and ethanol, slightly soluble in cold water. It decomposes free hydrocyanic acid into blue in aqueous solution. At room temperature, the decomposition takes place in about two weeks, and the speed increases when the temperature is higher than 65 ℃. Similar decomposition occurs in boiling ethanol. The melting point is 268-272 ℃ (decomposition).
