Properties

Description

Azido-PEG9-acid consists of a PEG molecule characterized by an azide moiety and a terminal carboxylic acid. The hydrophilic PEG spacer increases its solubility in aqueous media. The azide group can engage in reactions with alkynes, BCN, and DBCO via click chemistry processes to yield stable triazole formations. Furthermore, the terminal carboxylic acid can interact with primary amine groups when activated by agents like EDC or HATU.
