Along with N-hydroxysuccinimidyl, p-nitrophenyl, and phenylseleno esters, tetra- and penta-fluorophenyl esters were comparatively evaluated in term of their reactivity and hydrolytic stability. Their homobifunctional cross-linkers were prepared to conjugate proteins with small molecules, including carbohydrates, fluorescent dyes, and poly(ethylene glycol) monomethyl ether. The conjugations proceeded under mild conditions, affording the corresponding protein conjugates with good efficiency.
