(2R,4S)-Boc-D-Pro(4-N3)-OH (DCHA)

(2R,4S)-Boc-D-Pro(4-N3)-OH DCHA is a click chemistry reagent containing an azide. (2R,4S)-Boc-D-Pro(4-N3)-OH (DCHA) is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
