Used in analytical chemistry for the detection of iron(III) ions, producing a deep red coloration due to the formation of ferric thiocyanate complex. Commonly employed in qualitative and quantitative analysis in laboratories.

Utilized in the synthesis of other thiocyanate compounds and in organic chemistry as a source of thiocyanate ions for nucleophilic substitution reactions.

Applied in the mining industry for the extraction of gold and silver through thiocyanate leaching, offering an alternative to cyanide-based processes with lower toxicity. Also used in metal processing for electroplating (e.g., silver or gold) to enhance corrosion resistance and in the separation of certain rare metals from ores.

Used in some industrial formulations as a corrosion inhibitor and in certain types of photographic chemicals, such as in film developing processes.

Found in educational labs for classroom demonstrations involving colorimetric reactions and equilibrium studies.

Additionally, applied in biological and biochemical research, such as studying protein structures or controlling specific ion concentrations in solutions.
