Common Use | Azido-PEG4-CH2CO2-t-butyl ester is a PEG derivative containing an azide group and a t-butyl protected carboxyl group. The azide group enables Click Chemistry. The protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. The protected acid can be deprotected by acidic or basic hydrolysis. The hydrophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance when binding to streptavidin molecules. |
