Fl-DIBO is a fluorogenic dibenzocyclooctyne reagent used for bioorthogonal labeling of azide-containing molecules. It reacts rapidly with azides to form highly fluorescent products (excitation 363 nm, emission 469 nm), enabling sensitive labeling with low background.

• Fluorogenic probe for azide compounds enabling sensitive detection
• Rapid click chemistry reaction producing strong fluorescence (excitation 363 nm; emission 469 nm)
• High purity (~99.3%) and defined molecular weight (288.30)
• Available in small research quantities such as 10 mg
• Store at 4°C, protect from light; in solvent store at -80°C for long-term stability
