5-Ethynyl uridine (5-EU) is an alkyne-containing metabolic labeling reagent used to detect global RNA transcription temporally and spatially in both in-vitro and in-vivo with the modified nucleotide. The alkyne handler can be used for subsequent ligation to azide-containing molecules through a highly efficient click chemistry reaction.

5-Ethynyluridine is used to help detect RNA synthesis in cells by its biosynthetic incorporation into newly transcribed RNA.
