Common Name: Tetramethrin
Chemical Name: (1,3,4,5,6,7-Hexahydro-1,3-dioxo-2H-isoindol-2-yl) methyl 2,2-dimethyl-3-
CAS No. : 7696-12-0
HS Code: 38081090
Molecular Formula: C19H25NO4
Molecular Weight: 331.41
Physical Properties:
Technical grade tetramethrin is a colourless solid with a melting point of 65-800C. The specific gravity is 1.11 at 20 0C, and the vapour pressure is 0.946 mPa (7.1 x 10-6 mmHg) at 30 0C. It is sparingly soluble in water (4.6 mg/litre at 30 0C) but soluble in organic sol-vents such as hexane, methanol, and xylene. It is stable to heat but unstable to light and air. The [1R, cis/trans] isomer of tetramethrin is a yellow viscous liquid but otherwise has physical and chemical properties similar to tetramethrin.
Synthetic pyrethroids are neuropoisons acting on the axons in the peripheral and central nervous systems by interacting with sodium channels in mammals and/or insects. A single dose produces toxic signs in mam-mals, such as tremors, hyperexcitability, alivation, choreoathetosis, and paralysis. The signs disappear fairly rapidly, and the animals recover, generally within a week. At near-lethal dose levels, synthetic pyrethroids cause transient changes in the nervous system, such as axonal swelling and/or breaks and myelin degeneration in sciatic nerves. They are not considered to cause delayed neurotoxicity of the kind induced by some organophosphorus compounds.
