| Hazard Information | Back Directory | [Description]
m-PEG5-Tos is a PEG linker containing a tosyl group. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. | [Uses]
m-PEG4-Tos is a derivative of silybin ethers, extracted from patent CN105037337A (compound III-b). m-PEG4-Tos is a PEG-based PROTAC linker can be used in the synthesis of Silymarin (HY-W043277)[1]. | [IC 50]
