Polyethylene Glycol (PEGs & PEOs)

Bromo-PEG1-CH2CO2H is a PEG derivative containing a bromide group with a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond.

Bromo-PEG12-t-butyl ester is a PEG derivative containing a bromide group and a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic
