Used primarily in surface chemistry and nanotechnology, this compound serves as a key linker molecule for creating self-assembled monolayers (SAMs) on gold and other metal surfaces. The thiol group binds strongly to metals, while the bromine end provides a reactive site for further chemical modification, enabling the attachment of various functional groups or polymers. It is widely employed in biosensors, molecular electronics, and functionalized coatings due to its ability to form stable, ordered layers. Its long alkyl chain also contributes to hydrophobic properties and molecular insulation in electronic devices.
