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

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

Utilized in the mining industry for the extraction of gold and silver, where it serves as a less toxic alternative to cyanide in leaching processes.

Found in some metal treatment processes, including corrosion inhibition and metal cleaning formulations.

Used in the production of certain photographic chemicals and in some types of fingerprint detection techniques in forensic science.

Also applied in the preparation of artificial blood plasma substitutes and in some biomedical research settings for studying ion transport.
