BOC-D-MET-OSU is widely used in peptide synthesis as a protecting group for amino acids. It helps in the selective protection of the amino group during the formation of peptide bonds, ensuring that the desired sequence is achieved without unwanted side reactions. This compound is particularly useful in solid-phase peptide synthesis (SPPS), where it facilitates the stepwise assembly of peptides on a resin. Additionally, it is employed in the preparation of modified peptides and peptidomimetics, which are essential in drug discovery and development. Its stability under various reaction conditions makes it a reliable reagent for synthesizing complex peptide structures.
