This compound is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a building block for constructing peptides, where the Fmoc (fluorenylmethyloxycarbonyl) group acts as a protective group for the amino group during the synthesis process. The tert-butyl (tBu) group protects the serine side chain, ensuring selective reactions at the desired sites. Its application is crucial in producing peptides with high purity and precision, making it valuable in pharmaceutical research, drug development, and the study of protein structures and functions.
