Used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS), as a building block for creating custom peptides. It is valuable in the production of peptides for research, pharmaceuticals, and biotechnology due to its ability to protect amino groups during synthesis. The Fmoc group ensures selective deprotection, while the Boc group provides additional protection for the side chain, allowing precise control over peptide assembly. This compound is especially useful in synthesizing peptides with specific sequences or modifications, aiding in drug development and biochemical studies. Its application is critical in creating peptides with high purity and accuracy, essential for therapeutic and diagnostic purposes.
