Product Introduction

Coumarin 343 C3 Azide is a fluorescent labeling reagent used for bioorthogonal click chemistry. It contains a Coumarin 343 fluorophore attached to an azide functional group via a C3 linker. The azide moiety enables copper-catalyzed or strain-promoted azide-alkyne cycloaddition with alkyne-functionalized molecules. It is used for labeling proteins, peptides, and oligonucleotides, particularly in applications requiring UV-excitable blue fluorescence.
