Used as a fluorescent probe for detecting nitric oxide in biological systems due to its reaction with nitric oxide to form highly fluorescent triazoles. Employed in environmental analysis for the determination of nitrite in water samples through diazotization and coupling reactions. Acts as a precursor in the synthesis of heterocyclic compounds, including benzimidazoles and other nitrogen-containing rings used in pharmaceuticals. Applied in polymer chemistry as a crosslinking agent and curing agent for epoxy resins, enhancing thermal and mechanical stability. Also utilized in the development of chemosensors for metal ions owing to its chelating properties and signal transduction via fluorescence or color change.
