Used as a support resin in solid-phase organic synthesis, particularly in the preparation of peptides and other pharmaceutical compounds. Acts as a scavenger for acidic byproducts due to its basic pyridine groups, improving reaction efficiency and purity. Employed in the development of functional membranes and coatings with pH-responsive behavior, useful in sensors and controlled release systems. Applied in catalysis as a ligand stabilizer for metal nanoparticles, enhancing catalyst performance and recyclability. Also utilized in the formulation of adhesives and crosslinkable polymers for industrial coatings.
