4-(4-(丙-2-炔-1-基氧基)苯甲酰基)苯甲酸，4-(4-(Prop-2-yn-1-yloxy)benzoyl)benzoic acid；≥95%

4-(4-(Prop-2-yn-1-yloxy)benzoyl)benzoic acid is used for chemical probe synthesis, this trifunctional building block contains a light-activated benzophenone, alkyne tag, and carboxylic acid synthetic handle. When appended to a ligand or pharmacophore through its acid linker, this building block allows for 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.
