Used primarily in peptide synthesis, it serves as a protecting group for the amino acid serine. The Boc group safeguards the amino functionality during the coupling reactions, ensuring selective peptide bond formation. It is particularly valuable in solid-phase peptide synthesis, where it allows for the stepwise assembly of peptides. After the synthesis, the Boc group can be easily removed under acidic conditions without affecting the peptide backbone. This makes it a versatile tool in the production of complex peptides for research and pharmaceutical applications.
