Used as a redox-active building block in organometallic chemistry, particularly in the development of electroactive materials and sensors. Its stable ferrocene core with a bulky tert-butyl group enhances solubility in organic solvents and improves performance in thin-film applications such as molecular electronics and electrochemical detectors. Commonly employed in the synthesis of functionalized metallocenes for catalysis and in designing redox mediators in bioelectrochemistry. Also finds use in studying steric effects on electron transfer processes due to the electron-donating nature of the tert-butyl substituent.
