Used primarily as a protecting group reagent in organic synthesis, especially in peptide and pharmaceutical manufacturing. It enables selective protection of amine groups by forming carbamate derivatives, which are stable under various reaction conditions but can be removed when needed. Its bulky tert-amyl structure helps reduce side reactions and improves selectivity. Commonly applied in the synthesis of complex molecules where controlled reactivity and mild deprotection are required. Also utilized in research settings for developing new drug candidates and bioactive compounds.
