Application: Used for chemical probe synthesis, this trifunctional building block contains an aryl sulfonyl fluoride group, alkyne tag, and bromine synthetic handle. When appended to a ligand or pharmacophore through its brominated linker, this building block allows for SuFEx -enabled, context-specific covalent modification of a biological target with potential for downstream applications via the alkyne tag. Use alone or in parallel with other multi-functional building blocks  to discover the optimal probe for your chemical biology experiments.
