Used primarily as a key intermediate in peptide synthesis, this compound serves as a protecting group reagent, particularly for the selective protection of amino groups. Its structure allows for efficient coupling reactions in solid-phase and solution-phase peptide synthesis, enhancing purity and yield. It is especially valued in the preparation of complex peptides and proteins where orthogonality in protection strategies is required. Additionally, it finds use in the synthesis of bioactive molecules, including pharmaceuticals and enzyme inhibitors, due to its stability under various reaction conditions and ease of removal under mild acidic conditions.
