Ammonium thiocyanate (CAS 1762-95-4)

Ammonium thiocyanate, with the chemical formula NH4SCN, is a colorless crystalline salt renowned for its versatility in analytical chemistry and materials science research. It is extensively employed in titrations to determine the concentration of various metal ions, notably iron and silver, through the formation of visibly distinct complexes. The thiocyanate ion acts as a ligand, coordinating with metal ions to produce colored complexes, such as the red complexes with iron, which are crucial for accurate endpoint detection in colorimetric assays. This property is not only pivotal for analytical purposes but also facilitates the exploration of thiocyanate complexes in research focused on developing novel materials with unique magnetic and electronic properties. Furthermore, ammonium thiocyanate serves as a precursor in synthesizing other thiocyanate compounds, which are investigated for their potential in producing new herbicides, fungicides, and dyes. Its role in forming bridges between metal centers also opens avenues for studying advanced molecular architectures, contributing substantially to advancements in conductive materials and industrial chemistry applications.
