Used as a bifunctional protecting group reagent in peptide synthesis, enabling selective protection of amine functionalities in complex organic molecules. Its structure allows for controlled deprotection under mild acidic conditions, making it valuable in multi-step synthesis of pharmaceuticals and bioactive compounds. Commonly applied in the preparation of peptide conjugates and in solid-phase synthesis where orthogonal protection strategies are required. Also utilized in the development of prodrugs and functionalized polymers due to its stability and cleavability.
