DBCO-NHCO-PEG4-amine TFA salt - 98%, high purity , CAS No.1255942-08-5
DBCO-amine&DBCO-PEG-amine
Basic Description Specifications & Purity 98% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description DBCO-NHCO-PEG4-amine is a carboxyl-reactive building block with extended PEG spacer arm. The hydrophilic PEG spacer arm improves water solubility. In the presence of of activators (e.g. EDC, or DCC), this reagent can be used to derivatize carboxyl groups or activated esters (e.g. The NHS ester) through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions.
