Used primarily as a protecting group reagent in organic synthesis, particularly in peptide synthesis. It selectively protects amino groups by forming carbamate derivatives, which are stable under a variety of reaction conditions but can be removed when needed. Its long alkyl chain enhances lipophilicity, making it useful in modifying solubility properties of intermediates in multi-step syntheses. Also employed in the preparation of activated esters and in pharmaceutical manufacturing where controlled protection-deprotection sequences are required.
