Used in the fabrication of self-assembled monolayers (SAMs) on gold surfaces, enabling the development of molecular electronics and biosensors. The thiol group anchors the molecule to metal surfaces, while the ferrocenyl moiety provides reversible redox activity, making it valuable in electrochemical studies and charge-transfer research. It is also employed in creating functional interfaces for sensors, where its stable electrochemical behavior allows for signal amplification and detection. Additionally, it serves as a building block in supramolecular chemistry and nanotechnology for designing redox-switchable systems and conducting hybrid materials.
