m-PEG2-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.
m-PEG2-acid is a PEG-based PROTAC linker can be used in the synthesis of PROTACs.
ChEBI: 3-(2-methoxyethoxy)propanoic acid is a monocarboxylic acid that is propanoic acid substituted at C-3 by a 2-methoxyethoxy group. It has a role as a metabolite. It is a monocarboxylic acid and an ether.
