CAS 33213-65-9: β-Endosulfan

Description: β-Endosulfan is an organochlorine compound that belongs to the class of insecticides and acaricides. It is a stereoisomer of endosulfan, which is a mixture of two isomers: α and β. This compound is characterized by its white crystalline solid form and has a relatively low solubility in water, but it is more soluble in organic solvents. β-Endosulfan exhibits a high degree of lipophilicity, allowing it to bioaccumulate in the fatty tissues of organisms. It acts primarily as a neurotoxin, disrupting the normal functioning of the nervous system in insects by inhibiting the activity of gamma-aminobutyric acid (GABA), a key neurotransmitter. While effective in pest control, β-Endosulfan has raised environmental and health concerns due to its persistence in the environment and potential toxicity to non-target organisms, including humans. As a result, its use has been restricted or banned in several countries. Proper handling and application practices are essential to mitigate its risks.
