Description

Fensulfothion Po-Sulfone is a key organophosphorus compound and a significant metabolite of the insecticide fensulfothion. This compound is crucial for research and analytical purposes, particularly in environmental monitoring and toxicology studies to understand the degradation pathways and persistence of its parent molecule. It is primarily utilized by agrochemical research laboratories, environmental testing facilities, and regulatory bodies requiring high-purity reference standards for method development and residue analysis.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of equipment and validation of analytical methods in residue testing.
• Environmental Fate Studies: Critical for researching the degradation, metabolism, and environmental persistence of fensulfothion in soil and water systems.
• Toxicological Research: Employed in studies to determine the toxicity profile, metabolic pathways, and ecological impact of fensulfothion and its derivatives.
• Method Development & Validation: Essential for developing and verifying chromatographic (GC, LC) and spectroscopic methods in compliance with regulatory guidelines.
• Quality Control & Assurance: Used by manufacturers and testing laboratories to ensure the purity and consistency of fensulfothion-based products and to monitor for sulfone metabolites.
• Regulatory Compliance Testing: Supports testing for maximum residue limits (MRLs) in food and environmental samples as mandated by agencies like the EPA and EFSA.
