PEG

Benzyl-PEG6-Ms is a PEG linker containing a benzyl protecting group and a mesyl group. The benzyl moiety can be used as an alcohol protecting group and can be removed via hydrogenolysis. The mesyl group is a good leaving group for substitution reactions. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Benzyl-PEG2-amine is a PEG linker which contains a benzyl protecting group and a free amine. Benzyl groups can be used as alcohol protecting groups and can be removed via hydrogenolysis. The primary amine can react with carboxylic acids, activated NHS esters and other carbonyl compounds. The hydrophilic PEG linkers increase the water solubility of a compound in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
