“…Rapid (< 30 s) visual detection of hydrazine hydrate (2.5 ppb) using a 12 nm-AuNP-based colorimetric sensor with 2,6-pyridinedicarboxylic acid as a hydrogen-bonding motif has been reported. [45] The limit of detection (S/N = 3, 5 10 À8 m) was nearly four times lower than the threshold limit (10 ppb) set by the American Conference of Governmental Industrial Hygienists. The sensing process was evaluated based on the extinction ratio [(A 0 519 ÀA 519 )/A 0 519 ] re-sponse at various hydrazine hydrate concentrations, with the color of the solutions gradually changing from red to blue.…”

“…pure water. [35] Out of a family of carboxylates, hexanoate and dodecanoate led to a change of color from red to pale yellow at pH 7 (HEPES 0.001 m), leading to a polarity-induced transformation from merocyanine (44) to spirobenzopyran (45).…”

“…Intrinsically strong surface plasmon resonance (SPR), extremely high extinction coefficients in the visible wavelength range caused remarkable progress in the design of AuNPsbased colorimetric biosensors. There are some colorimetric methods based on gold nanoparticles for determination and detection of hydrazine [30][31][32][33][34][35][36].…”

Hydrazine and its analogues are widely used in agriculture and industry for the manufacture of metal films, photographic chemicals, antioxidants, preservatives, insecticides and blowing agents for plastics. It is also found in tobacco. It is used as a scavenger to remove traces of oxygen in boiler feed water system, as antioxidant in nuclear reactor, in military fuel cells and in electrical power plants. Hydrazine and its methyl substituted analogues and unsymmetrical dimethylhydrazine are commonly used as hypergolic propellants in space vehicles, intercontinental ballistic and in other military applications. In addition, hydrazine and its derivatives are considered to be carcinogens. Even low concentration of these substances results in toxic effects in humans. Therefore, there is a strong need in sensors for monitoring of hydrazines to ensure that they are below hazardous levels in order to minimize the risk of exposure. In this paper a brief review of recent spectrophotometric techniques and optical sensors for the determination of hydrazine and its analogues is presented. Kinetic and flow methods are discussed and compared as a part of spectrophotometric method. The review of optical sensors is divided into subsections based on application of nanoparticles, colorimetric and fluorescent sensors. The techniques of synthesis of new fluorescent reagents, their application for hydrazine detection by visual test method are described and compared. Indicator reactions and main techniques for the visual testing are described. This review comprises the results obtained after 2009.

4-Tetramethyldihydroquinoline (TMDQ) is formylated at the 6-position and the resulting quinoline aldehyde is condensed with 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one to obtain a merocyanine 6-pyrazolinyl TMDQ. The merocyanine is a selective and sensitive sensor for hydrazine hydrate in aqueous ethanolic medium and also for hydrazine gas. The merocyanine detects hydrazine hydrate selectively in less than 5 s over other amines, anions, and metals. The detection can be done simply by the naked eye and quantification can be done by absorbance/fluorescence spectroscopy. Hydrazine hydrate as well as hydrazine gas can be detected by the TLC plate technique.
