Sodium thiocyanate, represented by the chemical formula NaSCN, is an inorganic compound composed of sodium, sulfur, carbon, and nitrogen. It appears as a white crystalline solid and is highly soluble in water. This compound is often used in various applications, including as a reagent in chemical synthesis and in the production of certain dyes. In addition to its industrial uses, NaSCN plays a role in biological systems, where it can act as a source of thiocyanate ions. These ions are important in the human body, as they can influence thyroid function and are involved in detoxification processes.
