PEG methyl ether thiols

Browse Sigma-Aldrich and JenKem mPEG and PEG thiols

Nontoxic poly(ethylene glycol) (PEG) is one of the most widely applied drug delivery polymers, but its limited functionality poses some difficulty for researchers. We offer PEGs with a variety of functional groups to help accelerate your discovery in drug delivery. The poly(ethylene glycol) methyl ether products in the table below have functional thiol groups that react with maleimides, pyridyl disulfides, haloacetyls, vinylsulfones, and iodacetyls.

Quickly compare different products by functional thiol group (chemical structures shown) and price. We offer package sizes from 500 mg to 5 g. Click through to the product detail page to find polymer architecture information, empirical formula, molecular weight, purity, and applications.
