Widely used in solid-phase synthesis, particularly in peptide synthesis, where it serves as a polymer support for stepwise assembly of amino acids. Its functional groups allow for easy attachment of amino acid building blocks, enabling efficient and selective reactions with minimal side products. After synthesis, the final product can be cleaved from the resin under mild conditions, making it ideal for automated synthesizers. Also employed in combinatorial chemistry for generating compound libraries. Additionally, it finds use in purification processes and as a scavenger resin to remove excess reagents or byproducts in organic reactions.
