产品详情(用途,包装等)
PEG8-Tos is a PEG derivative containing a hydroxyl group with a tosyl group. The PEG linker contains 7 units of ethylene glycol. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The tosyl group is a very good leaving group for nucleophilic substitution reactions. |
