This compound is primarily used in peptide synthesis as a protecting group for amino acids. It helps prevent unwanted side reactions during the formation of peptide bonds. The Fmoc group is particularly useful in solid-phase peptide synthesis (SPPS) due to its stability under acidic conditions and ease of removal under basic conditions. The Hmb (2-hydroxy-4-methoxybenzyl) group provides additional protection against aggregation and improves the solubility of peptides, making it easier to synthesize longer and more complex peptides. This chemical is especially valuable in the production of therapeutic peptides and research involving peptide-based drug development.
