Description

Fensulfothion-Oxon CAS NO 6552-21-2 is an organophosphate compound and a key metabolite of the insecticide fensulfothion. This high-purity reference standard is critical for analytical research, environmental monitoring, and toxicological studies. It is primarily required by agrochemical manufacturers, analytical laboratories, and regulatory bodies for method development, quality control, and residue analysis.

Application

• Analytical Reference Standard: Used as a certified standard for the calibration of equipment and quantification of fensulfothion and its metabolites in various matrices via HPLC, GC-MS, or LC-MS.
• Environmental Monitoring: Essential for testing soil and water samples to assess environmental contamination and degradation pathways of the parent insecticide.
• Toxicology and Metabolism Studies: Serves as a critical reagent in research to understand the metabolic fate, toxicity profile, and biochemical impact of fensulfothion in biological systems.
• Agrochemical Research & Development: Utilized in the development and validation of analytical methods for product quality assurance and formulation analysis.
• Regulatory Compliance Testing: Employed by food safety and agricultural agencies to enforce maximum residue limits (MRLs) in crops and food products.
• Forensic Analysis: Applied in forensic investigations related to pesticide poisoning or misuse, providing a definitive identifier for the metabolite.
