Boc-L-Tyr (PEG (3) -N3) -OH (DCHA)

Boc-L-Tyr (PEG (3) -N3) -OH DCHA is a click chemistry reagent containing an azide group. This compound can participate in copper-catalyzed azide-alkyne cycloaddition (CuAAC) with molecules bearing an alkyne group. It is also capable of undergoing strain-promoted azide-alkyne cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.
