Polyethylene Glycol (PEGs & PEOs)

N-Boc-PEG4-alcohol is a PEG derivative containing a hydroxyl group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive

N-Boc-PEG4-bromide is a PEG derivative containing a bromide group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions.
