Properties

Description

Sulfo DBCO-PEG3-acid is a reagent grade analog of DBCO-Acid, featuring a PEG linker and a DBCO group for copper-free Click Chemistry reactions due to its strain-promoted high energy. The hydrophilic PEG chain and sulfo group enhance water solubility, and the terminal carboxylic acid can react with primary amine groups in the presence of activators to form a stable amide bond.
