Description

Endosulfan Lactone is a key chemical intermediate and metabolite of the organochlorine insecticide endosulfan. This compound is of significant interest in analytical chemistry and environmental science for monitoring and research purposes. It is primarily utilized by agrochemical manufacturers, analytical laboratories, and environmental testing facilities for method development, residue analysis, and toxicological studies.

Application

• Analytical Reference Standard: Serves as a certified standard for the accurate quantification of endosulfan and its metabolites in environmental and food samples via GC-MS or LC-MS.
• Environmental Fate Studies: Used in research to investigate the degradation pathways, persistence, and bioaccumulation of endosulfan in soil and water systems.
• Metabolite Identification: Essential for the identification and confirmation of endosulfan lactone as a metabolic product in toxicological and biological studies.
• Quality Control & Method Validation: Employed by agrochemical producers and testing labs to validate analytical methods and ensure the accuracy of purity assays for technical-grade endosulfan.
• Regulatory Compliance Testing: Supports testing protocols to comply with global regulations (e.g., EPA, EU) regarding pesticide residues and environmental contaminants.
