4-Mercaptopyridine（Cat No.:R051610）is a sulfur-containing heteroaromatic compound featuring a thiol (-SH) group at the 4-position of a pyridine ring. This molecule combines the nucleophilicity of the thiol group with the coordination ability of the pyridine nitrogen, making it useful in coordination chemistry, surface modification, and sensor design. It readily forms self-assembled monolayers (SAMs) on metal surfaces like gold, contributing to applications in nanotechnology and electrochemistry. Additionally, 4-mercaptopyridine can act as a ligand in metal-catalyzed reactions or as a reactive intermediate in the synthesis of sulfur-containing pharmaceuticals and materials.
