Description

Paraquat Monopyridone Iodide is a key chemical intermediate and reference standard of significant importance in agrochemical research and development. Its primary value lies in its role as a derivative and impurity marker for the widely used herbicide Paraquat dichloride, enabling precise analytical work and quality control. This compound is essential for manufacturers, analytical laboratories, and research institutions focused on herbicide synthesis, degradation studies, and environmental monitoring.

Application

• Analytical Reference Standard: Used as a certified standard in HPLC, LC-MS, and GC-MS for the quantification and identification of Paraquat and its metabolites in complex matrices.
• Agrochemical Impurity Profiling: Critical for monitoring and controlling the quality of technical-grade Paraquat formulations by identifying and quantifying specific process-related impurities.
• Environmental Fate Studies: Employed in research to understand the degradation pathways, persistence, and transformation products of Paraquat in soil and water systems.
• Metabolite Synthesis: Serves as a precursor or model compound in the synthesis of Paraquat metabolites for toxicological and pharmacokinetic studies.
• Method Development & Validation: Essential for developing and validating robust analytical methods in compliance with regulatory guidelines for agrochemicals.
• Forensic Analysis: Used in forensic laboratories for the definitive identification of Paraquat-related compounds in cases of contamination or poisoning.
