Product Information

Description	COOH-PEG10-COOtBu is a PEG linker containing a t-butyl-protected carboxyl group and 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 t-butyl-protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media.
Synonyms	Acid-PEG10-t-butyl ester; Acid-PEG10-C2-Boc; HOOCCH2CH2O-PEG9-CH2CH2COOtBu; COOH-PEG10-OtBu; 2,2-Dimethyl-4-oxo-3,7,10,13,16,19,22,25,28,31,34-undecaoxaheptatriacontan-37-oic acid; 4,7,10,13,16,19,22,25,28,31-Decaoxatetratriacontane-1,34-dioic acid, mono(1,1-dimethylethyl) ester
