Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. SDS of cas: 31643-49-9.
Olariu, Marius Andrei;Hamciuc, Corneliu;Asandulesa, Mihai;Hamciuc, Elena;Epure, Elena-Luiza;Tsakiris, Violeta;Lisa, Gabriela research published 《 Study on highly thermostable low-k polymer films based on fluorene-containing polyetherimides》, the research content is summarized as follows. Highly thermostable low-k polymer films with potential applications as dielec. materials in microelectronic industry were synthesized starting from 9,9-bis[4-(3,4-dicarboxyphenoxy)phenyl]fluorene dianhydride and various diamines. A polyetherimide/silica nanocomposite film was obtained using methyltriethoxysilane as precursor of inorganic phase. The chem. structure was confirmed by FTIR and 1H NMR spectroscopy. Water vapor’s sorption capacity, thermal stability, glass transition temperature, thermal diffusivity, sp. heat, thermal conductivity, and dielec. characteristics of the films were determined All the films exhibited excellent thermal stability, with an initial decomposition temperature in the range of 500-530°C. They showed low dielec. constant of 1.98-2.86 and low dielec. loss of 0.0037-0.011, at a frequency of 1 Hz and room temperature The subglass γ- and β-relaxations, primary α-relaxation, and conductivity relaxation processes were discussed according to the chem. structure of the samples. Quant. structure-property relationship (QSPR) study was conducted, and linear regression models were formulated to describe the causal relationships between different parameters and polyetherimide properties.
31643-49-9, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., SDS of cas: 31643-49-9
