Fmoc-Tyr(But)-OSu CAS:155892-27-6

Fmoc-Tyr(But)-OSu serves as a critical reagent in peptide synthesis, particularly in the selective modification of proteins and peptides. The OSu ester functionality allows for efficient coupling of tyrosine to amine-containing molecules or solid supports, facilitating the introduction of tyrosine residues at specific positions within a peptide sequence. The Fmoc group can be removed under mild conditions to expose the reactive OSu ester, enabling subsequent conjugation reactions. Furthermore, Fmoc-Tyr(But)-OSu finds extensive use in bioconjugation strategies for developing protein-drug conjugates, peptide-based imaging probes, and vaccine constructs. Its compatibility with solid-phase peptide synthesis enables the creation of custom peptide conjugates tailored for various biomedical applications, including targeted drug delivery and diagnostic tools. In summary, Fmoc-Tyr(But)-OSu plays a pivotal role in advancing bioconjugation and peptide chemistry research, empowering scientists and researchers to develop innovative conjugates and peptides with potential therapeutic, diagnostic, and research applications.
