Used in peptide synthesis as a protecting group for leucine, ensuring selective reactions during the formation of peptide bonds. It is particularly valuable in solid-phase peptide synthesis (SPPS) for constructing complex peptides and proteins. The compound also finds application in biochemical research for studying enzyme mechanisms and protein interactions. Additionally, it serves as an intermediate in the production of pharmaceuticals, especially those involving peptide-based drugs. Its stability and ease of removal make it a preferred choice in organic and medicinal chemistry.
