This chemical is primarily used in peptide synthesis, where it serves as a protected form of serine. The benzyl (Bzl) group protects the serine side chain during the synthesis process, preventing unwanted reactions. It is particularly useful in solid-phase peptide synthesis (SPPS) and solution-phase peptide synthesis, ensuring the selective formation of peptide bonds. Additionally, it finds application in the production of custom peptides for research in biochemistry, pharmacology, and drug development. Its stability and compatibility with various coupling reagents make it a valuable building block for creating complex peptide structures.
