Description

Vamidothion-Sulfone is a key chemical intermediate and metabolite of the organophosphate insecticide vamidothion. This compound is of significant interest for research and development in the agrochemical sector, particularly in the study of pesticide degradation pathways and environmental fate. It serves as a critical reference standard for analytical laboratories and manufacturers requiring high-purity materials for method development, quality control, and regulatory compliance.

Application

• Analytical Reference Standard: Primary use as a certified standard for HPLC, GC-MS, and LC-MS analysis in environmental and residue testing laboratories.
• Agrochemical Research: Critical for studying the metabolic pathways, environmental degradation, and persistence of vamidothion in soil and water systems.
• Metabolite Synthesis: Used as a building block or precursor in the synthesis of other metabolites for comprehensive toxicological and environmental impact studies.
• Quality Control: Employed by pesticide manufacturers to calibrate equipment and validate analytical methods for product purity and impurity profiling.
• Regulatory Compliance: Essential for generating data required for pesticide registration dossiers submitted to agencies like the EPA and EFSA.
