Synthesis and absorption properties of five new heterocyclic disazo dyes containing pyrazole and pyrazolone and their acute toxicities on the freshwater amphipod Gammarus roeseli<\/p>\n

In this study, five new heterocyclic disazo dyes containing pyrazole and pyrazolone were synthesised (3a-3e). The synthesised disazo dyes were characterised by elemental analysis and Fourier Transform-infrared and proton nuclear magnetic resonance spectroscopy. The effects of two different solvents upon the absorption ability of the dyes substituted with electron-withdrawing and electron-donating groups were examined in detail. In addition, the acute toxicity of each synthesised azo dye was evaluated using a short-term bioassay with Gammarus roeseli (Crustacea: Amphipoda) for 48 hours. According to the evaluations, the dyes 3a, 3b and 3d were categorised as slightly toxic, and the dyes 3c and 3e as practically non-toxic. Considering the toxicity of the dye 3a, it was determined that the substitution of the electron-withdrawing group in the azo dye resulted in more toxicity, while the substitution of the electron-donating group resulted in less toxicity. It was also found that the presence of the strongly electron-withdrawing group resulted in the azo dye becoming more toxic in comparison with the presence of the weakly electron-withdrawing group, but that the presence of the strongly electron-donating group resulted in the azo dye becoming less toxic in comparison with the presence of the weakly electron-donating group. It is contended that this study is novel and of great importance in terms of synthesising new azo dyes, investigating their absorption properties and assessing their acute toxicities.<\/p>\n
