Polyethylene Glycol (PEGs & PEOs)

m-PEG5-Ms is a PEG derivative containing a mesyl group. The mesyl group is a good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media.

m-PEG5-NHS ester is a PEG derivative containing an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases

m-PEG5-nitrile is a PEG derivative containing a nitrile terminal group. The nitrile group can undergo hydrolysis, reduction and other reactions. The hydrophilic PEG spacer increases the solubility of compounds in aqueous media.

m-PEG5-phosphonic acid ethyl ester is a PEG chain derivative. The hydrophilic PEG linkers increase the water solubility of compound in aqueous media. Longer PEG chains have better water solubility properties relative to shorter PEG chains.
