2-Mercaptobenzyl alcohol is primarily used in the field of organic synthesis as a versatile intermediate. Its unique structure, combining both thiol and alcohol functional groups, makes it valuable for constructing complex molecules. It is often employed in the preparation of pharmaceuticals, where it can serve as a building block for active pharmaceutical ingredients (APIs). Additionally, it finds application in the development of ligands for metal coordination chemistry, aiding in catalysis and material science. Its thiol group also makes it useful in surface modification and functionalization processes, particularly in creating self-assembled monolayers (SAMs) on metal surfaces. This chemical is also explored in the synthesis of polymers and resins, where it can enhance properties like adhesion and flexibility.
