Used as a surface modifier in nanomaterial synthesis, particularly for controlling the growth and stability of metal nanoparticles. The thiolate group binds strongly to metals like gold and silver, forming self-assembled monolayers that prevent aggregation and tailor surface properties. Commonly applied in the fabrication of sensors, catalysts, and conductive inks where precise nanoparticle dispersion is critical. Also utilized in studies of molecular electronics and interfacial chemistry due to its ability to form ordered, stable layers on conductive surfaces.
