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

(2R,4S)-H-D-Pro(4-N3)-OH is a click chemistry reagent containing an azide group. (2R,4S)-H-D-Pro(4-N3)-OH 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.
