Products Description of Sodium thiocyanate CAS#540-72-7
Sodium thiocyanate is a white crystal belonging to the rhombic system. It is soluble in water, ethanol, and acetone, with a relative density of 1.735 and a melting point of approximately 287℃. When heated or exposed to light, it decomposes and releases toxic fumes, including sulfur oxides, nitrogen oxides, and cyanides. Additionally, it reacts violently with acids, strong bases, and strong oxidants.
