Used as a key intermediate in click chemistry for the synthesis of functionalized molecules, particularly in pharmaceutical and bioconjugation research. Its triazole ring and ester group enable linkage to biomolecules or polymers, making it valuable in drug delivery systems and the development of targeted therapeutics. The tosylate functionality allows for further substitution reactions, facilitating the introduction of amines or other nucleophiles to tailor molecular properties. Commonly applied in the preparation of triazole-based peptidomimetics and as a building block in combinatorial chemistry for high-throughput screening libraries.
