QUINOXYFEN Usage And Synthesis
  • Chemical PropertiesOff-White Solid
  • UsesQuinoxyfen is under development for the control of powdery mildew in cereals and grapes.
  • UsesAgricultural fungicide.
  • DefinitionChEBI: A member of the class of quinolines carrying two chloro substituents at positions 5 and 7 together with a 4-fluorophenoxy substituent at position 4. A fungicide used mainly to control powdery mildew in cereals.
  • Metabolic pathwayQuinoxyfen is a novel fungicide for the control of powdery mildew in cereals. Its mode of action is unknown but it appears to differ from those of current fungicides and thus may be novel (Longhurst et al., 1996). Quinoxyfen is tightly bound to soil components and is somewhat persistent in this medium but in aqueous solution it is subject to rapid photodecomposition. Photodegradation is therefore likely to be an important process in its immediate removal from the environment. Plant metabolites have not been reported but unchanged quinoxyfen has been confirmed as the major residue.
    The compound is rapidly metabolised and eliminated following ingestion by rats and goats. Metabolism involves mainly hydroxylation of the intact quinoxyfen, cleavage at the ether bond and conjugation of the resulting metabolites. The information presented below was obtained from two sources (DowElanco, 1996; Reeves et al., 1996).
  • DegradationQuinoxyfen is stable in the dark at 25 °C and it is stable in aqueous solution at pH 7 and 9. Its DT50 at pH 4 was 16 days (40°C) but it was degraded more rapidly than this in light. Aqueous photolysis of dilute solutions occurs with DT50 values of 1.7 and 22.8 hours in June and December (Europe), respectively. The main degradation product was 2-chloro-10-fluoro[1]benzopyrano[2,3,4-de]quinoline (2, up to 30%); a second product (up to 11%) was probably 5,7-dichloro-4-hydroxyquinoline (3) (see Scheme 1).
