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. Quality Control of 31643-49-9.
Cong, Fangdi;Jiang, Hongzhen;Du, Xiguang;Yang, Wei;Zhang, Shulin research published 《 Facile, Mild-Temperature Synthesis of Metal-Free Phthalocyanines》, the research content is summarized as follows. It is important for the synthesis and research of phthalocyanine compounds for these compounds to be easily obtained at low temperature It was observed that metal-free phthalocyanine was sometimes found in a simple system used to synthesize phthalocyanine precursors at room temperature, and further studies showed that the key to the effective formation of phthalocyanines at low temperature lay in the presence of equal volumes of alc. and amine, in addition to substrate phthalonitriles and solvents, in the reaction system. A synthetic mechanism was proposed and facile syntheses have been realized, such as the synthesis of tetra-α(β)-nitrophthalocyanines and tetra-α(β)-(4- tert-butylphenoxy)phthalocyanines from the corresponding substituted phthalonitriles at mild temperature (37°C). The results are significant for the design and synthesis of new phthalocyanine derivatives, and the method is convenient and easy to adopt for general use in standard laboratories
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., Quality Control of 31643-49-9
