This chemical is primarily used in peptide synthesis, where it serves as a building block for constructing specific peptide sequences. Its benzyl-protected serine side chain ensures selective reactions during the synthesis process, preventing unwanted interactions. It is particularly valuable in solid-phase peptide synthesis (SPPS) for creating custom peptides used in research, drug development, and biochemical studies. Additionally, it is employed in the production of peptide-based pharmaceuticals, where precise control over amino acid incorporation is critical. Its stability and compatibility with various coupling reagents make it a reliable choice for synthesizing complex peptides with high purity and yield.
