Used in the fabrication of self-assembled monolayers (SAMs) on gold surfaces, enabling the development of electrochemical sensors and biosensors. Its ferrocene group provides reversible redox behavior, making it suitable for electron transfer studies and molecular electronics. Commonly employed in surface modification for electrocatalysis and in the design of redox-active interfaces for bioanalytical devices. Also utilized in fundamental research involving charge transport in organometallic thin films.
