150 results about "Anthranil" patented technology

Anthranil (2,1-benzisoxazole) is an organic compound with a molecular formula C₇H₅NO, which features a fused benzene-isoxazole bicyclic ring structure. It is an isomer of the more common compounds benzoxazole and benzisoxazole, with the oxygen atom being located in the 3-position. This arrangement disrupts the aromaticity of the molecules by cross-conjugation, making it by far the least stable of the 3 structural isomers.
