3-Azido-7-hydroxycoumarin is a water soluble coumarin derivative. 3-Azido-7-hydroxycoumarin is able to undergo highly selective and high yielding Cu(I) catalysed cycloaddition reactions with terminal alkynes (Huisgen cycloaddition or ''click chemistry) to afford the corresponding 1,2,3-triazole under relatively mild reaction conditions. The triazoles thus formed, like 7-hydroxycoumarine, are highly fluorescent and, as 3-azido-7-hydroxycoumarin itself does not fluoresce, terminal alkyne containing molecules can be effectively tagged and visualised by fluorescence spectroscopy. Synonyms: 3-Azido-7-hydroxy-2H-1-benzopyran-2-one, 3-Azido-7-hydroxy-2H-chromen-2-one CAS No: 817638-68-9 Molecular Formula: C9H5N3O3 Molecular Weight: 203.15 Purity (HPLC): 98% Appearance: Amber to brown powder 1H-NMR Spectrum: Conforms to reference Melting Point: 107-110C (lit) Storage and Stability: Store at -20C. Product is stable for 6 months after receipt.
