  • Applications

    5-Aminopentane-2-thiol, CAS number: 1522334-82-2, is primarily used as a building block in the synthesis of specialty chemicals and pharmaceutical intermediates, leveraging its thiol and amino functionalities for further transformations. It can act as a ligand or chelating agent in metal-catalyzed processes and coordination chemistry, enabling the formation of metal complexes. In polymers and surface science, it is used to functionalize polymers and modify surfaces or nanoparticles by providing reactive thiol and amine handles for grafting or coupling with systems. In coatings and adhesives, it can participate in thiol–ene and amine–epoxy chemistries to enhance network formation or enable post-functionalization. Additionally, it may be used as a sulfur-containing odorant component in fragrance formulations, subject to formulation constraints and regulatory considerations.
