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., Product Details of C8H3N3O2
Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves.

Butler, Tristan;Bunton, Caleb;Ryou, Heonjune;Dyatkin, Boris;Weise, Nickolaus;Laskoski, Matthew research published 《 Influence of molecular weight on thermal and mechanical properties of bisphenol A-based phthalonitrile resins》, the research content is summarized as follows. This effort assesses the correlation between chem. structures and performance-essential thermal, mech., and long-term stability properties of cross-linked thermosets. Resins of different mol. weights were prepared from the Bisphenol A based PEEK-like oligomeric phthalonitrile (BisA). Differential scanning calorimetry, which was used to investigate curing thermodn., indicated that BisA resins demonstrated pos. correlation between increasing oligomer mol. weight and both resulting m.ps. and cure initiation conditions. Characterization of thermal properties using thermogravimetric anal. (TGA) indicated a similar mol. weight trend, with char yields ranging between 57% and 73%. Rheol. studies of BisA of different mol. weights indicated significant viscosity increases in phthalonitriles that crosslinked from oligomers with higher mol. weights Moreover, the n = 1 chain length resin exhibited a gel point at 100°C lower than the n = 25 oligomer. Anal. of hardness of these cured polymers indicated that the resin crosslinked using the n = 1 oligomer was most brittle, while the thermoset derived from the n = 4 BisA demonstrated highest hardness. Aging of cured phthalonitriles indicated that the n = 10 remained most stable in long-duration high-temperature environments. This study suggests the use of preparing BisA thermosets from oligomers with different mol. weights as an effective strategy for improving toughness, albeit at the tradeoff of lower thermal stabilities.
