Primarily used in peptide synthesis as a protecting group for the amino acid arginine. It helps prevent unwanted side reactions during the coupling of amino acids, ensuring the correct sequence in peptide chains. Commonly employed in pharmaceutical research and development for creating peptides with specific biological activities. It is also utilized in biochemical studies to investigate protein interactions and functions. The Boc group can be easily removed under acidic conditions, making it a versatile choice in organic and medicinal chemistry.
