What is 2,5,8,11,14-pentaoxahexadecan-16-oic acid ?
Description
m-PEG5-CH2COOH 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.
