CAS 72-20-8: Endrin

Description: Endrin is a synthetic organic compound classified as a cyclodiene insecticide, primarily used in agricultural applications. It is characterized by its colorless to pale yellow appearance and has a distinct odor. Endrin is known for its high toxicity to a wide range of organisms, including insects, birds, and aquatic life, which has led to significant environmental concerns. Its chemical structure features a complex arrangement of carbon, hydrogen, and chlorine atoms, contributing to its stability and persistence in the environment. Endrin is lipophilic, meaning it tends to accumulate in fatty tissues of living organisms, leading to bioaccumulation and potential biomagnification in food chains. Due to its hazardous nature, the use of endrin has been banned or severely restricted in many countries. It is important to handle this substance with caution, adhering to safety regulations to mitigate risks to human health and the environment.
