Used as an activating agent in peptide synthesis, this compound facilitates the coupling of amino acids by forming active esters that react efficiently with amine groups. It is particularly useful in solid-phase peptide synthesis where high yields and minimal racemization are required. Additionally, it serves as a linker in bioconjugation, enabling the attachment of molecules such as drugs, labels, or probes to proteins or other biomolecules through its bromoalkyl functional group. The compound's stability and reactivity make it suitable for preparing functionalized polymers and in the development of pharmaceutical intermediates.
