Primarily utilized in bioconjugation and click chemistry applications, this compound serves as a versatile linker for attaching molecules, particularly in the development of pharmaceuticals and biomaterials. Its trifluoroethyl group enhances stability, while the PEG2 spacer improves solubility and reduces steric hindrance, making it ideal for coupling reactions. The azide group enables efficient and selective click chemistry reactions, such as with alkynes, to form stable triazole linkages. This is particularly useful in drug delivery systems, where precise and controlled attachment of therapeutic agents is required. Additionally, it is employed in the synthesis of fluorescent probes and imaging agents, aiding in biological research and diagnostics. Its unique properties make it a valuable tool in material science for creating functionalized surfaces and polymers.
