Used as a stabilizer in certain types of photographic emulsions and in the production of thiourea and other thiocyanate compounds. Commonly applied in the textile industry for the synthesis of synthetic fibers like rayon. Employed in the mining sector for the extraction of gold and silver through thiocyanate leaching, offering an alternative to cyanide-based processes. Utilized in laboratories as a reagent for qualitative inorganic analysis, especially in the detection of iron and copper ions. Also found in some formulations for cold wave solutions in hair perming due to its ability to break and reform disulfide bonds in keratin.
