Product Information

Description	Br-PEG6-CH2COOH is a PEG linker containing a bromide group with 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. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions.
Synonyms	Bromo-PEG6-CH2CO2H; Bromo-PEG6-acetic acid; 20-Bromo-3,6,9,12,15,18-hexaoxaicosan-1-oic acid; Acetic acid, 2-[(17-bromo-3,6,9,12,15-pentaoxaheptadec-1-yl)oxy]-; 3,6,9,12,15,18-Hexaoxaeicosan-1-oic acid, 20-bromo-
