Chlorfenvinphos is an organophosphate insecticide and acaricide used to control a variety of pests. It is known for its effectiveness against insects such as flies, fleas, and ticks. Chlorfenvinphos works by inhibiting the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system in insects.

Chemical Properties[edit | edit source]

Chlorfenvinphos is a colorless to amber liquid with a mild odor. It is soluble in organic solvents but has low solubility in water. The chemical formula for chlorfenvinphos is C12H14Cl3O4P, and its molecular weight is 373.57 g/mol.

Usage[edit | edit source]

Chlorfenvinphos is primarily used in agricultural settings to protect crops from insect damage. It is also used in veterinary medicine to control parasites on livestock. The compound can be applied in various forms, including sprays, dusts, and emulsifiable concentrates.

Mode of Action[edit | edit source]

As an organophosphate, chlorfenvinphos inhibits the enzyme acetylcholinesterase, leading to an accumulation of acetylcholine in the nervous system. This causes continuous nerve impulse transmission, resulting in paralysis and death of the insect.

Health and Environmental Effects[edit | edit source]

Chlorfenvinphos is toxic to humans and animals if ingested, inhaled, or absorbed through the skin. Symptoms of poisoning include headache, dizziness, nausea, and muscle twitching. Due to its toxicity, the use of chlorfenvinphos is regulated in many countries.

Regulation and Safety[edit | edit source]

The use of chlorfenvinphos is subject to strict regulations to minimize its impact on human health and the environment. Personal protective equipment (PPE) is recommended for individuals handling the chemical. Additionally, there are guidelines for the safe disposal of chlorfenvinphos to prevent environmental contamination.
