Ammonium thiocyanate, 98+%, Thermo Scientific Chemicals

Description

Ammonium thiocyanate has many uses in manufacturing chemicals such as metal thiocyanates [CuSCN, Ca(SCN)₂, NaSCN, KSCN] and in a number of pharmaceuticals. It is used in freezing solutions, pickling, printing, and as a corrosion inhibitor against acid gases. It is used in the photography industry as a stabilizer or an accelerator. It is also used in fertilizers, fabric dyeing, zinc coating, electroplating and as a separator of zirconium and hafnium as well as gold and iron. It is also used in analytical chemistry for titrimetric analysis and to determine the iron content by colorimetry in soft drinks.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
