6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile(cas: 50743-32-3) belongs to nitriles. Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons.Safety of 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile

Safety of 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrileOn March 31, 1986, Hayashi, Nobuyoshi; Imanishi, Masayuki published an article in Journal of Labelled Compounds and Radiopharmaceuticals. The article was 《Synthesis of 2-amino-7-isopropyl-5-oxo-5H-[1]benzopyrano[2,3-b][2-14C]pyridine-3-carboxylic acid (AA-673-14C)》. The article mentions the following:

Ester I (R = Et) was prepd by cyclocondensation of NC14CH2CO2Et with cyanochromone II in the presence of piperidine. I (R = Et) was hydrolyzed to give the title compound (I, R = H). After reading the article, we found that the author used 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile(cas: 50743-32-3Safety of 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile)

2-(4-Bromo-3-indolyl)acetonitrile(cas: 89245-35-2) is a member of nitriles. Nitriles have been reduced to amines by many methods, especially by catalytic hydrogenation and by metal hydrides. Aliphatic and aromatic nitriles have also been reduced to nitro derivatives using hydrazinium monoformate in the presence of Raney-nickel.Product Details of 89245-35-2

Mao, Qiu-Xia; Zhang, Chen-Guang; Li, Jin-Feng published their research in Acta Crystallographica, Section E: Structure Reports Online on February 29 ,2012. The article was titled 《2-(4-Bromo-1H-indol-3-yl)acetonitrile》.Product Details of 89245-35-2 The article contains the following contents:

In the title compound, C10H7BrN2, the non-H atoms, except the N atom of the acetonitrile group and the C atom bonded to it, lie in the least-squares plane defined by the atoms of the indole ring system (r.m.s deviation = 0.019 Å), with the N and C atom of the cyano group displaced by 2.278 (1) and 1.289 (1) Å, resp., out of that plane. In the crystal, N-H···N hydrogen bonds link the mols. into a C(7) chain along [100]. Crystallog. data are given.2-(4-Bromo-3-indolyl)acetonitrile(cas: 89245-35-2Product Details of 89245-35-2) was used in this study.
