Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 50743-32-3, name is 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 50743-32-3
REFERENCE EXAMPLE b 1 In carbon tetrachloride (300 ml) was suspended 6-isopropyl-4-oxo-4H-1-benzopyran-3-carbonitrile (10.65 g). To the suspension was added N-bromosuccinimide (8.90 g). The mixture was subjected to reflux for two hours under irradiation of infrared ray lamp (Toshiba, 100 V, 375 WR). The resultant was then cooled to room temperature, followed by removal of insolubles by filtration. The filtrate was concentrated under reduced pressure. The concentrate was dissolved in ethyl acetate (150 ml), which was washed with water three times, dried and concentrated. The precipitating crystals were collected by filtration to give 6-(1-bromo-1-methylethyl)-4-oxo-4H-1-benzopyran-3-carbonitrile as colorless prisms (7.0 g). Melting point: 115-117 C.
According to the analysis of related databases, 50743-32-3, the application of this compound in the production field has become more and more popular.
