MPEG6-CH2CH2COOH Chemical Properties,Uses,Production

Description

m-PEG7-acid is a PEG linker containing a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.

Uses

Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization

General Description

Monodisperse PEG. COOH group is stable and can be activated.
