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., Computed Properties of 31643-49-9

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. Computed Properties of 31643-49-9.

Li, Jian;Wu, Minjie;Rong, Jianxin;Zhang, Qian;Yu, Xiaoyan;Zhang, Qingxin research published 《 Synthesis and Properties of Phthalonitrile Polymer with a Novel Piperazine Structural Curing Agent》, the research content is summarized as follows. A novel autocatalytic phthalonitrile (PN) monomer containing piperazine structure, namely 4-[1-(4-aminophenyl)-4-(4-phenyl)piperazine-oxy]phthalonitrile (APPN), is synthesized from the nucleophilic substitution reaction of 1-(4-aminophenyl)-4-(4-hydroxyphenyl)piperazine and 4-nitrophthalonitrile. The structure of the APPN monomer is characterized by NMR (NMR) spectroscopy and Fourier Transform IR (FTIR) spectroscopy. The novel 4-nitrophthalonitrile end-capped compound APPN is firstly used to promote the curing reaction of PN monomer 1,3-bis(3,4-dicyanophenoxy)benzene (m-BDB). Thermogravimetric Anal. (TGA) and Dynamic Mech. Anal. (DMA) showed that the PN resin in the presence of 10% of APPN possessed outstanding thermal and thermo-oxidative stabilities as well as good mech. properties, better than the properties of those with 20% of APPN and 10% of APPH. Its glass transition temperature (Tg) is higher than 400°, and the polymer loses 5% of its weight (T5%) at 524° and shows a storage modulus of 1373 MPa at 400°.
