• Description: Potassium ferricyanide is a coordination compound, appearing as a bright red salt under standard conditions. It's structure consists of potassium ions coordinated with the ferricyanide ligand ([Fe(CN)6]^3-). Potassium ferricyanide can be categorized as a coordination compound or an inorganic salt.
• Uses and Mechanism of Action: Potassium Ferricyanide is widely used in electrochemical impedance spectroscopy (EIS) for redox probing and as a chemiluminescent reagent for various assays, including telomerase activity detection. In EIS, potassium ferricyanide serves as a redox probe, undergoing reversible oxidation and reduction reactions. In chemiluminescence assays, it undergoes oxidation in the presence of singlet oxygen, resulting in the generation of a chemiluminescent signal.
