High-sensitivity hydrazine detection kit and application thereof

The invention relates to high-sensitivity hydrazine detection kits and application thereof, in particular to kits with 4-bromobutyrate tricyano furan styrene compounds serving as long-wavelength hydrazine colorimetric fluorescent probes. The probes are not only high in selectivity in hydrazine recognition but also flexible in hydrazine qualitative and qualitative analysis carried out at long-wavelength positions according to a fluorescence method. The probes are capable of quickly responding to hydrazine to realize real-time hydrazine detection and capable of realizing hydrazine qualitative and qualitative analysis only by 'naked eye' observation and are available for long-term storage and use due to property stability. In addition, the probes have excellent anti-interference performances. Synthesis conditions of the probes are mild relatively, and the probes can be synthesized simply only by one-step reaction.
