Product Description
α-hydroxyl-ω-propionic acid poly(ethylene glycol) (HO-PEG-propionic acid) is a linear heterofunctional PEG with hydroxyl on one end and carboxyl group on the other. It is a useful cross-linking reagent with a PEG spacer. There is a ethylene (CH2CH2) linkage between PEG and COOH, often called propionic acid. Heterobifunctional PEG products with other carboxylic acid such as GA (glutaric acid), SA (succinic acid), GAA (glutaramide acid), and SAA (succinimide acid) may be offered through our custom synthesis service.
