Description

It is an ester of 2-(4-chlorophenyl)-3-methylbutyric acid and alpha-cyano-3-phenoxybenzyl alcohol but lacks a cyclopropane ring. However, in terms of its insecticidal behaviour, it belongs to the pyrethroid insecticides. Technical grade fenvalerate is a yellow or brown viscous liquid having a specific gravity of 1.175 at 25°C. The vapour pressure is 0.037 mPa at 25°C, and it is relatively non-volatile. It is practically insoluble in water (approximately 2 μg/L) but soluble in organic solvents s
