Description

cis-Mevinphos CAS NO 338-45-4 is a specific stereoisomer of the organophosphate insecticide Mevinphos, known for its potent acetylcholinesterase inhibition. This high-purity compound is critical for research and development in agrochemical science, particularly in the study of insecticidal activity and environmental fate. It serves as a key analytical standard and reference material for laboratories in the agricultural, environmental monitoring, and regulatory compliance sectors.

Application

• Analytical Reference Standard: Primary use as a high-purity standard for calibrating equipment and validating analytical methods (e.g., GC, HPLC) in residue analysis.
• Agrochemical Research & Development: Critical for studying structure-activity relationships, metabolic pathways, and degradation products of organophosphate insecticides.
• Environmental Fate Studies: Used in research to understand the persistence, mobility, and breakdown of mevinphos in soil and water systems.
• Toxicological Studies: Employed in laboratories to investigate the mechanism of toxicity, exposure effects, and safety thresholds.
• Quality Control & Method Development: Serves as a benchmark for manufacturers and testing labs to ensure the accuracy and reliability of their analytical procedures for mevinphos detection.
• Regulatory Compliance Testing: Essential for laboratories that perform testing to ensure compliance with international maximum residue limits (MRLs) in food and environmental samples.
