Uses
Azido-PEG4-CH2CO2H is a useful research chemical.
Description
Azido-PEG4-CH2CO2H is a very popular click chemistry linker containing an azide group with a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU).
Uses
N33-TEG-COOH (N3-TEG-COOH) is a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1]. N33-TEG-COOH 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.
reaction suitability
reaction type: click chemistry
reagent type: linker
