| Hazard Information | Back Directory | [Description]
Propargyl-PEG3-Tos is a PEG linker containing a tosyl group and a propargyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. | [Uses]
Tos-PEG2-O-Propargyl is a PEG-based PROTAC linker can be used in the synthesis of Thalidomide-O-PEG2-propargyl (HY-126458)[1]. Tos-PEG2-O-Propargyl is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups. | [IC 50]
