[Description]

m-PEG5-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-PEG5-acid is a PEG-based PROTAC linker can be used in the synthesis of PROTACs.
