Thiourea, white bright crystals, bitter taste, soluble in cold water, ethanol, slightly soluble in ether, easy to deliquescence in air, converted into ammonium thiocyanate at 150 °C, with reducing property, can reduce free iodine to iodine ions.
High-purity thiourea is a fine chemical with extremely high purity and very low impurity content. Compared with ordinary thiourea, high-purity thiourea has higher purity and lower impurities. It is not only a deep processing product of ordinary industrial-grade thiourea, but also an indispensable key raw material in many high-tech fields.
