Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. 10111-08-7, formula is C4H4N2O, Name is 1H-Imidazole-2-carbaldehyde. Their solubility in alcohol is lower than that in water and decreases with increasing molecular weight of the alcohols . Recommanded Product: 1H-Imidazole-2-carbaldehyde.
Li, Mengde;Liu, Junjie;Deng, Shuping;Liu, Qian;Qi, Ning;Chen, Zhiquan research published 《 Low-pressure CO2 capture in zeolite imidazole frameworks with ultramicropores studied by positron annihilation》, the research content is summarized as follows. In this paper, three kinds of zeolite imidazole frameworks (ZIF-90, ZIF-93, and ZIF-94) were synthesized through hydrothermal reactions. Positron lifetime results reveal two kinds of pores corresponding to the channel in the windows and central cavity of ZIFs. The average diameters of the cavities are 1.12, 1.54, and 0.80 nm in ZIF-90, ZIF-93, and ZIF-94, resp., while the average diameters of channels are between 0.55 and 0.60 nm. CO2 adsorption results show that ZIF-90 has the highest CO2 adsorption capacities (64.4 cm3 g-1 at 298 K and 104.7 cm3 g-1 at 273 K) at 1 bar, followed by ZIF-94 (57.9 cm3 g-1 at 298 K and 79.4 cm3 g-1 at 273 K) and ZIF-93 (41.5 cm3 g-1 at 298 K and 62.5 cm3 g-1 at 273 K). This shows inconsistency with the total pore volume but is in good agreement with relative volumes of pores smaller than 1.2 nm, which are 6.55, 2.06, and 5.60% for ZIF-90, ZIF-93, and ZIF-94, resp. Further investigation reveals that an even smaller pore size is required for CO2 adsorption under ultralow pressure. At a pressure of 0.1 bar, ZIF-94 exhibits an ultrahigh CO2 adsorption capacity (21.2 cm3 g-1 at 298 K and 32.1 cm3 g-1 at 273 K) compared with ZIF-93 (10.1 cm3 g-1 at 298 K and 14.9 cm3 g-1 at 273 K) and ZIF-90 (5.9 cm3 g-1 at 298 K and 11.6 cm3 g-1 at 273 K). These quantities coincide well with the relative volumes of pores smaller than 0.8 nm, which are 5.60, 2.06, and 1.18% for ZIF-94, ZIF-93, and ZIF-90, resp. Our results demonstrate that at atm. pressure, CO2 mols. are more effectively captured by micropores, while at extremely low pressures, CO2 mols. are mainly enriched around ultramicropores such as the channels and small cavities in ZIFs.
10111-08-7, 1H-Imidazole-2-carbaldehyde, also known as 1H-Imidazole-2-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%.
1H-Imidazole-2-carboxaldehyde is a novel PTP1b inhibitor with potential application to treat type 2 diabetes.
1H-Imidazole-2-carboxaldehyde is a broad-spectrum antimicrobial that has been shown to inhibit the growth of bacteria by interfering with protein synthesis. It binds to the cytosolic protein and receptor molecule, which are involved in the activation of bacterial enzymes. Imidazole-2-carboxaldehyde reacts with anhydrous sodium and copper complex to produce hydrogen bonds, which prevent the formation of the nitrogen atoms necessary for cellular processes. This chemical also has biological properties such as glyoxal, which inhibits bacterial growth by reacting with amino groups on proteins., Recommanded Product: 1H-Imidazole-2-carbaldehyde
