Usage

Description

KADETHRIN is a pyrethroid insecticide specifically designed to control household pests such as houseflies, mosquitoes, and cockroaches. It is known for its effectiveness in eliminating these pests and is often used in combination with other pyrethroid insecticides and synergists to enhance its performance.

Uses

Used in Household Pest Control:
KADETHRIN is used as an insecticide for controlling various household pests, including houseflies, mosquitoes, and cockroaches. Its application helps in maintaining a clean and healthy living environment by reducing the presence of these insects that can cause discomfort and transmit diseases.
Used in Combination with Other Insecticides and Synergists:
KADETHRIN is often used in combination with other pyrethroid insecticides and synergists to improve its effectiveness in controlling pests. This combination approach allows for a more potent and targeted treatment, ensuring the elimination of a wider range of pests and reducing the likelihood of resistance development.

Metabolic pathway

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.
