Used primarily in peptide synthesis, this compound serves as a building block for creating custom peptides. It is particularly valuable in solid-phase peptide synthesis (SPPS), where the Fmoc group protects the amino group during the coupling process. This allows for the sequential addition of amino acids to form peptides with high precision. It is widely applied in research and development of pharmaceuticals, especially in the production of peptide-based drugs. Additionally, it plays a role in studying protein structures and functions, aiding in the design of therapeutic agents. Its stability and compatibility with various solvents make it a preferred choice in laboratory settings.
