Application

4-Mercaptobenzoic acid is widely used as a linker molecule for gold nanoparticle (AuNP) functionalization due to its strong Au?CS binding affinity. It serves as a precursor for self-assembled monolayers (SAMs) in biosensor development and surface-enhanced Raman spectroscopy (SERS). The compound is also employed in peptide synthesis and as a building block for pharmaceutical intermediates.
