The azide group (N3) reacts with terminal alkynes to produce a stable triazole

monosulfo is azide-activated fluorescent dyes for chemoselective labeling and detection of alkyne-tagged molecules

The two-step reaction procedure involves a copper-catalyzed triazole formation of an azide and an alkyne

Tetramethylrhodamine-5 C2 maleimide Size:5mg 5-ROX azide is an excellentAlthough tetramethylrhodamine (TMR) maleimides and iodoacetamides are popular thiol reactive labeling reagents, they are quite unstable in water, and the commercial tetramethylrhodamine maleimides and iodoacetamides often have lower purities than other tetramethylrhodamine labeling reagents (such as TAMRA SE reagents) due to their synthetic difficulties. In addition, the labeling efficiency of tetramethylrhodamine maleimides and iodoacetamides is
