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., Formula: C8H3N3O2

Zhang, Heng;Li, Minghui;Wang, Caiyun;Huang, Gang;Liu, Meina;Sun, Jing;Fang, Qiang research published 《 A highly heat-resistant phthalocyanine resin based on a bio-based anethole》, the research content is summarized as follows. A phthalonitrile-containing monomer derived from a plant oil (anethole) has been successfully synthesized by a facile two-step reaction in an overall yield of 84%. Upon high temperature, this monomer is converted to a cured phthalocyanine resin in the presence of a catalyst, 4,4′-bis(3-aminophenoxy)diphenyl sulfone (m-BAPS). Such a cured resin displays good thermostability including high glass transition temperature (Tg > 450°C), low thermal expansion coefficient (CTE, near 62.99 ppm °C-1 from 25 to 400°C) and high char yield (>72% at 1000°C). These data are comparable to those of the most of the common phthalocyanine resins derived from the fossil resource, suggesting that the phthalonitrile-containing monomer is a suitable precursor for the preparation of the ablation-resistant materials used on the surface of the spacecrafts.
