| Hazard Information | Back Directory | [Description]
Azido-PEG3-S-PEG4-t-butyl ester is a PEG linker containing one azide group and one t-butyl protected carboxyl group. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. | [Uses]
Azido-PEG3-S-PEG4-t-butyl ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azido-PEG3-S-PEG4-t-butyl ester is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups. | [IC 50]
