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. Recommanded Product: 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.

Recommanded Product: 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrileOn October 25, 1985 ,《Synthesis of the metabolites and degradation products of 2-amino-7-isopropyl-5-oxo-5H-[1]benzopyrano[2,3-b]pyridine-3-carboxylic acid (amoxanox)》 was published in Chemical & Pharmaceutical Bulletin. The article was written by Ukawa, Kiyoshi; Ishiguro, Toshihiro; Kuriki, Hisashi; Nohara, Akira. The article contains the following contents:

Benzopyranopyridinecarboxylic acid I (R = CHMe2), a promising drug for bronchial asthma, was converted to various degradation products, I (R = CMe2OH, CHMeCH2OH, COMe), which were also synthesized from benzopyranonitrile. On testing for passive cutaneous anaphylaxis in rats, I (R = CHMe2, CMe2OH, COMe) were 260 times as potent as disodium cromoglycate (DSCG) while I (R = CMeCH2OH) was 1500 times as potent as DSCG. In the experimental materials used by the author, we found 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile(cas: 50743-32-3Recommanded Product: 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile)
