What is S-Bioallethrin?

Chemical properties

S-Bioallethrin is a yellow liquid. It is miscible with most organic solvents. S-Bioallethrin is the ester of the (1R, trans)-acid with (1S)-allethrolone. S-bioallethrin is a synthetic pyrethroid with fast knock-down activity against household pest insects. It is several times as effective as allethrin against flying and crawling insects. It is used in public health applications against mosquitoes, houseflies and cockroaches.

The Uses of S-Bioallethrin

S-Bioallethrin, by far the most potent constituent of allethrin, is a contact insecticide with rapid knockdown effect. Its effectiveness is enhanced by the addition of a synergist such as piperonyl butoxide or MGK 264 in pesticide formulations. It is used in aerosols, coils or sprays indoors against flying and crawling insects.

Definition
