The drug is found in the form of either colorless crystals or yellowish brown semisolid mass and has a density is 1.28g/ml at 20oC.
The IUPAC name of Cypermethrin is [cyano-(3-phenoxyphenyl)methyl]3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropane-1-carboxylate and its molecular formula is C22H19Cl2NO3. The drug is canonicalized and its topological surface area is 59.3 A^2. The molecular weight of the compound is 416.298 g/mol. It affects the sodium ion channels on nerve cell membranes. The toxicity of the drug depends on the precise ratio of cis- and trans-species present in mixtures. It is available in a solid form in its pure form while isomers are semi-solid or liquid.
Deltamethrin helps in controlling malaria vectors due to its insecticidal properties. It belongs to the class of synthetic pyrethroids. Its IUPAC name is [(S)-cyano-(3-phenoxyphenyl)methyl] (1R,3R)-3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropane-1-carboxylate and the chemical formula is C22H19Br2NO3. The drug is utilized to eliminate household pests particularly spiders, fleas, ticks, carpenter ants, and cockroaches. It is able to modulate sodium channels in the nerve cell membrane and enhance the release of neurotransmitter which helps in increasing protein phosphorylation activities.
Ethion is a colorless or amber colored liquid with a pungent smell. It is basically used in agricultural sector as a pesticide to control insects on citrus or cotton trees. The compound has molecular formula C9H22O4P2S4 and molar mass of 384.459 g/mol. It is also recognized by several other names such as Ethopaz, Nialate, Niagara 1240, and Diethion. This pesticide is available in the form of dry mixture where the liquid is absorbed into a dry carrier.
The IUPAC name of Permethrin is 3-Phenoxybenzyl (1RS)-cis,trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate and the chemical formula is C21H20Cl2O3. It belongs to the family of pyrethroids and is a kind of insecticide mainly used to treat lice infestations and scabies. The color of this compound is yellow to light orange-brown and it is available as low melting solid or viscous liquid. It acts on the nerve cell membrane and blocks the sodium channel current which results in delayed repolarization and paralysis of the pests.
