4H-1-Benzopyran-4-one,6-fluoro-2,3-dihydro- (66892-34-0)

 6-Fluoro-4-chromanone (66892-34-0) is acid and derivative which also can be called for 6-fluoro-2,3-dihydro-4H-chromen-4-one ; 2-Chloro-6-fluorobenzonitrile ; 4H-1-benzopyran-4-one, 6-fluoro-2,3-dihydro- .It can be used for sorbinil intermediates.You can take Acetaminophen as raw materials to get the production by  the role of etherification, cyclization, hydrolysis, diazotization, and fluorine.
 6-Fluoro-4-chromanone (66892-34-0) is hazardous,so the first aid measures and others should be known.Such as: When on the skin: first,should  flush skin with plenty of water immediatelyfor at least 15 minutes while removing contaminated clothing. Secondly,Get shoesmedical aid .
