Description

Acetochlor Esa Sodium Salt is the sodium salt form of the primary environmental metabolite of the pre-emergent herbicide acetochlor. This compound is of significant importance for environmental monitoring, regulatory compliance, and agrochemical research. It serves as a critical analytical reference standard for laboratories and institutions involved in the detection and quantification of acetochlor residues in soil and water. Professionals in the agrochemical, environmental testing, and contract research sectors require this high-purity material to ensure accurate risk assessment and adherence to global environmental protection standards.

Application

• Environmental Fate and Metabolism Studies: Used as a certified reference material to study the degradation pathways and environmental persistence of the herbicide acetochlor.
• Analytical Method Development & Validation: Essential for developing and calibrating sensitive analytical methods (e.g., LC-MS/MS, HPLC) for trace-level detection in complex matrices.
• Regulatory Compliance Testing: Acts as a primary standard for laboratories conducting mandatory residue analysis to comply with EPA, EU, and other international regulatory limits in soil and groundwater.
• Quality Control in Agrochemical Manufacturing: Employed in internal QC labs of herbicide producers to monitor and control the levels of this specific metabolite in technical products or formulations.
• Ecotoxicity and Risk Assessment Research: Provides a pure substance for scientific studies evaluating the ecological impact and toxicological profile of acetochlor degradation products.
