METHOXYPOLYETHYLENE GLYCOL 5,000 PROPIONIC ACID Chemical Properties,Uses,Production
Description
m-PEG24-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
m-PEG-acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
