• 용도

  Kadethrin is used to control household pests, particularly houseflies, mosquitoes and cockroaches. It is normally used in combination with other pyrethroid insecticides and synergists.

• 신진 대사 경로

  Kadethrin is used almost wholly indoors and therefore little has been published on its environmental fate. Information on its photodegradation and metabolism in rats has been reported.

• Degradation

  Kadethrin is unstable to heat and it is rapidly decomposed by light. It is hydrolysed in aqueous alkaline solution to (E)-(1R)-cis-2,2-dimethyl-3- (2-oxothiolan-3-ylidenemethyl)cyclopropanecarboxylic acid (2), 5-benzyl- 3-furylmethanol (3) and its thiolactone ring-opened derivative (5) (Scheme 1).
  Products of photodecomposition have been reported by Ohsawa and Casida (1979). Photo-hydrolysis of kadethrin occurs on sunlight irradiation affording 2 and 5 and 5-benzyl-3-furancarboxylic acid (4), presumably via the alcohol (3). cis-trans Isomerisation of the cyclopropane ring and E-Z interconversion about the double bond was also noted. Thus, from the lRcisE isomer (kadethrin), all of the possible isomers were found to varying degrees (ie. 1RScis-trans-E-Z mixtures).
  Photo-hydrolysis products (e.g. 2 and 5) were also found aS isomers. The facility of the isomerisation process was considered to be due to resonance stabilisation of a triplet diradical, one form of which (6) is shown in Scheme 1. Kadethrin also yielded a lactone (7) derived from the cyclopropane ring. Photo-oxidation of the alcohol moiety analogous to that reported for resmethrin was also found. The hydroxylactone (8) and the benzyloxylactone (9) were reported (but the hydroxycyclopetenolone [resmethrin, 61) was absent.
