Used in peptide synthesis as a protecting group for serine, ensuring selective reactions during the assembly of peptide chains. It is particularly valuable in solid-phase peptide synthesis (SPPS) where the Fmoc group provides temporary protection, while the Trt group safeguards the hydroxyl side chain of serine. This allows for precise control over the peptide-building process, minimizing unwanted side reactions. It is widely applied in the production of therapeutic peptides, research peptides, and biochemical studies. The compound’s stability and compatibility with standard SPPS protocols make it a reliable choice for synthesizing complex peptides with high purity and yield.
