Fluorescent probes for hydrazine

A fluorescent probe based on benzoyl hydrazine was synthesized and characterized as an Al3+-selective fluorescent probe. This probe showed good selectivity towards Al 3+ compared to other common ions. Under optimized experimental conditions, the probe exhibited a linear dynamic response for Al 3+ from 5.0 × 10−7 to 4.5 × 10−6 M with a detection limit of 1.3 × 10−7 M in ethanol–water solution (9:1, v:v, pH 6.8, 20 mM HEPES). Furthermore, it was used for imaging of Al3+ in living cells with satisfying results.

Hydrazine (N2H4) is an important and commonly used chemical reagent for the preparation of textile dyes, pharmaceuticals, pesticides and so on. Despite its widespread industrial applications, hydrazine is highly toxic and exposure to this chemical can cause many symptoms and severe damage to the liver, kidneys, and central nervous system. As a consequence, many efforts have been devoted to the development of fluorescent probes for the selective sensing and/or imaging of N2H4.
