Description

Phosmet-Oxon is a key organophosphate metabolite and analytical reference standard, primarily used for environmental monitoring and toxicological research. This compound is critical for laboratories and manufacturers requiring precise quantification of pesticide residues and breakdown products. It is essential for quality control in agrochemical production, regulatory compliance testing, and advanced research into metabolic pathways within the global agricultural and environmental science sectors.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating equipment in Gas Chromatography (GC) and Liquid Chromatography (LC) methods for residue analysis.
• Environmental Monitoring: Detection and quantification of Phosmet degradation products in soil, water, and crop samples to assess environmental impact.
• Toxicology Studies: Research into the metabolism, mode of action, and toxicological profile of organophosphate insecticides.
• Agrochemical Quality Assurance: In-process testing and final product verification for manufacturers of Phosmet and related pesticide formulations.
• Regulatory Compliance Testing: Supporting labs in meeting global MRL (Maximum Residue Limit) standards set by agencies like the EPA, EFSA, and FDA.
• Method Development & Validation: A critical component in developing and validating new analytical methods for pesticide residue testing.
