This compound is primarily utilized in peptide synthesis, where it serves as a protected form of serine. The tert-butyl groups protect the serine's hydroxyl and carboxyl functionalities, preventing unwanted reactions during the peptide chain assembly. This protection is crucial in solid-phase peptide synthesis (SPPS), enabling the selective deprotection and coupling of amino acids to build complex peptides. It is particularly valuable in the production of therapeutic peptides, where precise sequence control is essential. Additionally, its stability and ease of handling make it a preferred choice in research laboratories for developing peptide-based drugs or studying protein interactions.
