What Is Dieldrin?
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.
Uses of Dieldrin
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.
Properties of Dieldrin
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.
Types of Dieldrin
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.
Other Information on Dieldrin
1. Synthesis of Dieldrin
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.
2. Mechanism of Action of Dieldrin
As a pesticide, dieldrin’s believed mechanism involves the disruption of GABA receptors in pests, leading to neuroexcitation, convulsions, and insecticidal effects.
3. Toxicity of Dieldrin
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.
4. Regulatory Information on Dieldrin
Due to its hazardous properties, dieldrin is subject to strict regulations under various laws, necessitating correct handling and compliance with safety standards.
