Properties

Description

Azido-PEG3-aminoacetic acid-NHS ester functions as a PEG linker incorporating an azide group along with an NHS ester functionality. The hydrophilic nature of the PEG spacer increases its solubility in water-based media. Similar to previous products mentioned, its azide moiety can participate in click chemistry reactions with alkyne compounds like BCN or DBCO leading to stable triazole formations.
