Hydroxyl di-benzophenone (PEG)₃ alkyne is used for chemical probe synthesis, this trifunctional building block contains two light-activated benzophenones, an alkyne tag, and carboxylic acid synthetic handle. When appended to a ligand or pharmacophore through its acid linker, this building block allows for dual UV light-induced 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.

Light and moisture sensitive(Benzophenone is UV-light activated).
