The product is further processed (without being isolated) by a solution of potassium thiocyanate in hydrochloric acid.

Common derivatives include the colourless salts potassium thiocyanate and sodium thiocyanate.

Potassium thiocyanate is the chemical compound with the molecular formula KSCN.

In addition, the relatively low number of disulfide bonds could account for instability of C5 when exposed to chaotrophs such as potassium thiocyanate.

Closely related reagents include ammonium thiocyanate and potassium thiocyanate, which has twice the solubility in water.

Allyl isothiocyanate is produced commercially by the reaction of allyl chloride and potassium thiocyanate:

This reaction reverses above 1200 K. A laboratory synthesis entails the reaction potassium thiocyanate and sulfuric acid.

In this titration, glucose reduces cupric ions to cuprous ions which react with potassium thiocyanate to produce a white precipitate, indicating the endpoint.

The archival Gold Protective Solution (GP-1) formula uses a 1% gold chloride stock solution with sodium or potassium thiocyanate.

NHSCN is weakly acidic; reacts with caustic soda or caustic potash to form sodium thiocyanate or potassium thiocyanate.

The salts are composed of the thiocyanate ion (SCN) and a suitable metal cation (e.g., potassium thiocyanate, KSCN).

The reaction of potassium thiocyanate and sulfuric acid yielded a gas containing significant amount of byproducts (HCN, HO and CS) and required purification.

One study's results showed that it produced (in order of descending quantities): 55.91% solid products: potassium carbonate, potassium sulfate, potassium sulfide, sulfur, potassium nitrate, potassium thiocyanate, carbon, ammonium carbonate.
