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.

Endosulfan II

Controlled Product

CAS: 33213-65-9

Endosulfan II, an organochlorine insecticide and a stereoisomer of Endosulfan I, effectively targets various insects such as bollworms and tobacco budworms, with lethal doses (LD50s) of 4.14 and 4.95 mg/g, respectively. It interacts with GABA receptors in rat brain membranes, demonstrating an inhibition concentration (IC50) of 60 nM. Notably, Endosulfan II exhibits lower toxicity in rats compared to Endosulfan I, with LD50 values of 240 and 18 mg/kg, respectively.
