Product Information

Description	Tos-PEG10-O-CH3COOH is a PEG linker containing a tosyl group and a terminal carboxylic acid. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.
Synonyms	Tos-PEG11-CH2COOH; Tos-PEG10-CH2COOH; 32-(tosyloxy)-3,6,9,12,15,18,21,24,27,30-decaoxadotriacontanoic acid
