Description

Vamidothion Sulfoxide is a key organophosphorus compound and a primary metabolite of the insecticide vamidothion. This intermediate is critical for research and development in the agrochemical sector, particularly in the study of pesticide metabolism, environmental fate, and analytical method development. It serves as an essential reference standard for quality control laboratories and R&D departments focused on crop protection science and regulatory compliance.

Application

• Analytical Reference Standard: Primary use as a high-purity certified standard for calibrating equipment and quantifying vamidothion and its metabolites in environmental and biological samples.
• Agrochemical Research & Development: Critical intermediate for studying the metabolic pathways, degradation profiles, and environmental impact of vamidothion-based insecticides.
• Metabolite Synthesis: Used in the synthesis and study of further degradation products for comprehensive toxicological and environmental monitoring programs.
• Quality Control & Assurance: Employed by manufacturers and testing laboratories to verify the purity of active ingredients and to monitor for sulfoxide residues in formulations.
• Regulatory & Compliance Testing: Essential for conducting residue studies required for pesticide registration and approval by global regulatory bodies (e.g., EPA, EFSA).
