“…When an acetic acid solution of hydrazine and monomethylhydrazine is treated with salicylaldehyde in the presence of perchloric acid, only the unsubstituted hydrazine reacts with salicylaldehyde. The excess perchloric acid is titrated with standard sodium acetate solution and the perchloric acid consumed is a measure of the monomethylhydrazine present (123).…”

“…On the one hand, most of the hydrazine fluorescent probes were designed from the Schiff base based on aldehyde group's reactivity to the hydrazine [25][26][27][28][29][30][31][32]. On the other hand, a new method based on Gabriel type-based hydrazinolysis was explored to detect hydrazine recently [1,33,34].…”

A novel coumarin-based fluorescent probe CF was synthesized for the detection of hydrazine both in aqueous solution and vapor state with high sensitivity and selectivity. Upon addition of hydrazine, the solution of probe CF in MeCN-H2O (3/7, v/v, buffered CH3COOH/CH3COONa) at pH 5.0 exhibited a remarkable change in emission color from pale green to light blue, which could be recognized with naked eyes. Applied in weak acid condition, probe CF could detect hydrazine selectively with large amount of unknown environments according to the competing tests. Besides, with the limit of detection 8.32 ppb (2.6 × 10(-7) M), probe CF could well meet the request (10 ppb) of the U.S. Environmental Protection Agency (EPA).
