Description and uses: an important pseudohalide compound, highly soluble in water and soluble also in acetone.

With Fe3+(aq) (ferric ion) it forms a blood red complex; FeSCN2+, a property used in analytical chemistry as a visual test for ferric ions. A KSCN solution is used in volumetric analysis as an indicator solution for redox titrations, using acidified ferric ammonium alum as titrant solution.

The red colour of the FeSCN2+ complex causes NH4SCN to be used for creating blood effects for film or theatre.
