Properties

Description

Azido-PEG4-CH₂CO₂H represents a widely used linker featuring an azide group along with a terminal carboxylic acid functionality suitable for click chemistry applications. The hydrophilic PEG spacer increases solubility in aqueous media while allowing the azide moiety to react with alkyne compounds like BCN or DBCO through click chemistry methods to create stable triazole linkages. Moreover, the terminal carboxylic acid can interact with primary amines when activated by agents such as EDC or HATU.
