BOC-Oxyma is widely used in peptide synthesis as a coupling reagent. It facilitates the formation of amide bonds between amino acids, enhancing efficiency and reducing racemization. Its application is particularly valuable in solid-phase peptide synthesis (SPPS), where it ensures high yields and purity of the synthesized peptides. Additionally, it is employed in the preparation of complex peptides and proteins for pharmaceutical research and drug development. BOC-Oxyma is also utilized in organic synthesis for esterification and other coupling reactions, making it a versatile tool in chemical laboratories.
