Description

Application

4-(Fluorosulfonyl)-3-((trimethylsilyl)ethynyl)benzoic acid is used for chemical probe synthesis, this trifunctional building block contains an aryl sulfonyl fluoride group, alkyne tag, and carboxylic acid synthetic handle. When appended to a ligand or pharmacophore through its acid 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.
