CAS 72-55-9: p,p′-DDE

Description: p,p′-DDE, or 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene, is a persistent organic pollutant and a breakdown product of the pesticide DDT (dichlorodiphenyltrichloroethane). It is characterized by its lipophilic nature, which allows it to accumulate in the fatty tissues of living organisms, leading to biomagnification in the food chain. p,p′-DDE is a colorless to pale yellow solid at room temperature and is relatively stable, exhibiting low volatility. It is poorly soluble in water but soluble in organic solvents, which contributes to its environmental persistence. The compound has been associated with various ecological and health concerns, including endocrine disruption, as it can mimic estrogen and interfere with hormonal systems in wildlife and humans. Due to its environmental impact, p,p′-DDE is subject to regulatory scrutiny and monitoring in various ecosystems, particularly in areas previously treated with DDT. Its detection in biological samples often serves as an indicator of past DDT usage and environmental contamination.
