Panoramica
Ms-PEG3-Ms are PEG derivatives with two mesyl groups. The mesyl groups are good leaving groups and can also be used as protecting groups for primary alcohols. They can be deprotected in the presence of sodium amalgam. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media.
This compound belongs to the class of organic compounds known as organosulfonic acid esters. These are esters of sulfonic acid, which have the general structure RS(=O)2OR' (R,R' = organyl, not H).
