(4-(2-(2-(2-Aminoethoxy)ethoxy)ethoxy)phenyl)(4-(prop-2-yn-1-yloxy)phenyl)methanone is a trifunctional building block for chemical probe synthesis, typically employed for photoaffinity labeling in chemcial biology and medicinal chemistry. It contains a light-activated benzophenone (photoreactive group), terminal alkyne tag (clickable handle), and amine synthetic handle (connectivity group). When appended to a ligand or pharmacophore through its PEGylated amine linker, this probe building block allows for UV light-induced covalent modification of a biological target with potential for downstream applications via the alkyne tag.
