This chemical is primarily used in peptide synthesis as a protected form of serine. It serves as a building block to incorporate serine into peptide chains while protecting the hydroxyl group from unwanted reactions during the synthesis process. The tert-butyl group ensures stability and selectivity, making it a valuable component in the production of complex peptides for research and pharmaceutical applications. Its use is particularly significant in creating peptides with specific structures or functions, such as those used in drug development or biochemical studies.
