Used in click chemistry reactions due to the azide group, enabling bioconjugation and labeling of biomolecules. The trifluoromethylsulfane moiety enhances lipophilicity and metabolic stability, making it valuable in pharmaceutical research for developing drug candidates with improved bioavailability. Commonly employed in the synthesis of probes for fluorescence imaging and target identification in biological systems. Also applied in material science for surface functionalization and polymer modification through copper-catalyzed azide-alkyne cycloaddition (CuAAC) or strain-promoted azide-alkyne cycloaddition (SPAAC).
