Cyanoferrocene is widely used in electrochemical applications due to its unique redox properties. It serves as a redox mediator in biosensors, enhancing the detection of biomolecules like glucose and cholesterol. In organic synthesis, it acts as a precursor for synthesizing ferrocene derivatives, which are valuable in catalysis and material science. Additionally, cyanoferrocene is employed in the development of molecular electronics and as a component in non-linear optical materials. Its stability and electron-transfer capabilities make it a key compound in research focused on energy storage and conversion technologies.
