Used as a building block in organometallic chemistry for synthesizing redox-active ligands and polymers. Its aldehyde groups allow for easy functionalization via condensation reactions, making it valuable in creating Schiff bases and other derivatives for catalysis. Commonly employed in the development of sensors due to the electrochemical properties of the ferrocene core, especially in detecting ions and small molecules. Also applied in materials science for designing conductive or electroactive polymers and molecular wires. Its reversible redox behavior supports use in electrochemical studies and devices such as molecular switches.
