Description

Terbufos-Sulfone is a key organophosphate metabolite and environmental degradate of the insecticide Terbufos. This compound is of significant importance for analytical reference and environmental monitoring, serving as a critical marker for residue analysis and ecological impact studies. It is primarily needed by agrochemical manufacturers, analytical laboratories, and regulatory bodies involved in pesticide fate research and food safety compliance.

Application

• Analytical Reference Standard: Used as a high-purity certified standard for the accurate quantification of Terbufos and its metabolites in environmental and agricultural samples via GC-MS or LC-MS.
• Environmental Fate Studies: Employed in research to track the degradation pathways, persistence, and mobility of Terbufos in soil and water systems.
• Residue Analysis: Essential for testing compliance with Maximum Residue Limits (MRLs) in crops, soil, and water, ensuring food safety and regulatory adherence.
• Metabolite Profiling: Used in toxicological and metabolic studies to understand the biotransformation of Terbufos in plants and organisms.
• Quality Control: Serves as an in-house control material for agrochemical producers to monitor the quality and consistency of their Terbufos-based formulations.
• Method Development & Validation: A critical component for developing, calibrating, and validating analytical methods in accredited testing laboratories.
