Application

Potassium hexacyanoferrate(III) [Potassium ferricyanide] has been used as an oxidant in the preparation of diethidium and di-mito-ethidium. It reacts with cobalt chloride hexahydrate to afford CoHCF (Cobalt hexacyanoferrate) nanoparticles.
It may be employed as an oxidizing agent during the fabrication of glucose conductometric biosensor.

General description

Potassium hexacyanoferrate(III) (Potassium ferricyanide) can be prepared by the anodic oxidation of K4[Fe(CN)6].
