Properties

Description

Methylamino-PEG1-acid HCl salt is a PEG linker featuring a terminal carboxylic acid and a methylamine group, provided as a hydrochloride salt for stability. The carboxylic acid group allows coupling with primary amines in the presence of activators such as EDC or HATU to form stable amide bonds. The methylamine group reacts with carboxylic acids and carbonyls, and the PEG1 spacer enhances water solubility.
