Propargyl-PEG4-Ms has an alkyne group and a mesylate group. The mesylate group is a sulfonate ester for nucleophilic substitution reactions (SN2). The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environments. Reagent grade, for research use only.
