Product Information

Description	m-PEG12-COOH 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.
Synonyms	mPEG11-CH2CH2COOH; mPEG12-acid; mPEG11-propionic acid; m-PEG12-acid; 2,5,8,11,14,17,20,23,26,29,32,35-dodecaoxaoctatriacontan-38-oic acid; alpha-Methoxy-omega-propioic acid undeca(ethylene glycol); O-(2-Carboxyethyl)-O'-methyl-undecaethylene glycol; 4,7,10,13,16,19,22,25,28,31,34,37-Dodecaoxaoctatriacontanoic acid
