Dieldrin is an organic compound with the formula C12H8Cl6O, recognized by its norbornane ring structure and CAS number 60-57-1. Globally, the production and use of dieldrin are largely prohibited due to its designation as a persistent organic pollutant under the Stockholm Convention.
Historically, dieldrin was utilized in pesticides, termite repellents, wool product insect repellents, wood preservatives, and paint additives. However, due to safety concerns and environmental persistence, its use has been discontinued.
As a crystalline solid with a melting point of 176-177°C and a boiling point of 385°C, dieldrin is chemically stable, persistent in the environment, and practically insoluble in water. Its high persistence posed significant environmental and health risks, leading to its discontinuation.
With industrial applications now obsolete, dieldrin is primarily found as a standard for pesticide residue analysis, available as a pure substance or in mixtures for laboratory use.
Synthesized via a Diels-Alder reaction and subsequent epoxidation, dieldrin can also form in nature through the epoxidation of aldrin. Endrin is a stereoisomer of dieldrin.
As a pesticide, dieldrin's believed mechanism involves the disruption of GABA receptors in pests, leading to neuroexcitation, convulsions, and insecticidal effects.
Dieldrin's hazardous effects on human health and the environment categorize it under multiple GHS classifications, including acute toxicity, carcinogenicity, reproductive toxicity, and specific target organ toxicity. Its environmental hazard status requires careful handling and disposal.
Due to its hazardous properties, dieldrin is subject to strict regulations under various laws, necessitating correct handling and compliance with safety standards.
