Description

Demeton-S-Methyl Sulfone is a key organophosphorus compound and the primary metabolite of the insecticide demeton-S-methyl. This compound is of significant interest in analytical chemistry and environmental science for its role as a reference standard and marker for pesticide residue analysis. It is essential for laboratories and research institutions focused on environmental monitoring, food safety testing, and toxicological studies. The product is supplied as a high-purity analytical standard to ensure reliable and reproducible results.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of analytical instruments and method validation in pesticide residue analysis.
• Environmental Monitoring: Used in the detection and quantification of demeton-S-methyl and its metabolites in soil, water, and air samples to assess environmental contamination.
• Food Safety Testing: Critical for laboratories conducting residue analysis on agricultural products to ensure compliance with Maximum Residue Levels (MRLs) and food safety regulations.
• Toxicology and Metabolism Studies: Employed in research to study the metabolic pathways, environmental fate, and toxicological profile of organophosphorus insecticides.
• Quality Control in Manufacturing: Serves as a benchmark for the quality control of technical-grade pesticide formulations.
• Forensic Analysis: Used in forensic laboratories for the identification of specific pesticide compounds in casework investigations.
