The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . 3034-50-2, formula is C4H4N2O, Name is Imidazole-4-carbaldehyde. In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with an increase of the alkyl chain length of the alcohols. Category: imidazoles-derivatives.
Zhang, Qianqian;Yang, Shuang;Wang, Jun;Cheng, Jianwen;Zhang, Qiaoxin;Ding, Guoping;Hu, Yefa;Huo, Siqi research published 《 A DOPO based reactive flame retardant constructed by multiple heteroaromatic groups and its application on epoxy resin: curing behavior, thermal degradation and flame retardancy》, the research content is summarized as follows. A high-efficiency flame retardant composed of phosphaphenanthrene, benzothiazole and imidazole groups (PBI) was synthesized and served as flame retardant co-curing agent to reduce the fire hazard of epoxy resin (EP). The chem. structure of PBI was characterized by Fourier transform IR spectroscopy (FTIR), high-resolution mass spectroscopy (HR-MS), 1H and 31P NMR. The curing behavior, thermal stability and flame retardant properties of the prepared EP systems were investigated. The curing behavior study disclosed that PBI accelerated the crosslinking reaction of EP and was chem. bonded with EP matrix to obtain intrinsic flame retardant thermoset. The resulting EP thermosets showed only slight decrease in glass transition temperature (Tg). The thermogravimetric anal. (TGA) results indicated both the catalytic decomposition and catalytic charring effects of PBI demonstrated by decreased thermal stability and enhanced charring capability of EP/DDS/PBI thermosets. The combustion test results showed remarkable improvement in the flame retardant properties of EP/DDS/PBI thermosets. When the phosphorus content was only 0.75 wt%, EP/DDS/PBI-0.75 thermoset achieved a limiting oxygen index (LOI) value of 34.6% and passed UL94 V-0 rating. Moreover, the peak of heat release rate (pk-HRR), average of heat release rate (average-HRR) and total heat release (THR) values were decreased by 48.7%, 31.1% and 28.3%, resp., in comparison with those of the EP/DDS thermoset. The flame retardant effect of PBI on EP was attributed to the catalytic charring effect to form protective char layer in condensed phase and release of free radicals with quenching effect and nonflammable gases with diluting effect in gaseous phase.
Category: imidazoles-derivatives, 1H-Imidazole-4-carbaldehyde, also known as 1H-Imidazole-4-carbaldehyde, is a useful research compound. Its molecular formula is C4H4N2O and its molecular weight is 96.09 g/mol. The purity is usually 95%.
The starting material for a practical synthesis of a potent C17,20-lyase inhibitor. The lyase is a key enzyme in androgen biosynthesis as well as a target for treatment of androgen-dependent prostate cancer. Used to synthesize potent antimalarial drug.
1H-Imidazole-4-carbaldehyde is a chemical compound that has been shown to bind to the glucocorticoid receptor. It was synthesized by reacting 1,2-diaminobenzene with formaldehyde and then hydrolyzing the intermediate imidazolium salt, which is stable in acidic solutions. The complex can be prepared by mixing two solutions of imidazole and trifluoroacetic acid. The ligand has a redox potential of -0.1 V (vs NHE). This means it can be oxidized to the carbonyl group or reduced back to the imidazole ring. The compound is stable in neutral solution and forms stable complexes with metal ions such as Cu+, Fe3+, and Zn2+. It also coordinates well with oxygen atoms, nitrogen atoms, and water molecules. 1H-Imidazole-4-carbaldehyde has been shown to bind to glucocortic, 3034-50-2.
