Description

Metolachlor-2-Hydroxy is a key metabolite and degradation product of the widely used chloroacetamide herbicide, Metolachlor. This compound is of significant importance in environmental monitoring, analytical research, and the study of agrochemical degradation pathways. It serves as a critical analytical reference standard for laboratories in the agrochemical, environmental testing, and regulatory compliance sectors, enabling accurate quantification and fate analysis of the parent herbicide in various matrices.

Application

• Analytical Reference Standard: Primary use as a high-purity certified standard for calibrating equipment and validating methods in environmental and residue analysis.
• Environmental Fate Studies: Used in research to track and understand the degradation, metabolism, and persistence of Metolachlor in soil and water systems.
• Metabolite Identification: Essential for the identification and confirmation of Metolachlor metabolites in plant, animal, and environmental samples.
• Regulatory Testing & Compliance: Supports testing for regulatory bodies (e.g., EPA, EU) to monitor groundwater and food safety compliance regarding herbicide residues.
• Method Development & Validation: A critical component in developing and validating new analytical techniques such as LC-MS/MS, GC-MS, and HPLC for precise detection.
• Toxicological Research: Employed in studies assessing the ecotoxicological impact and behavior of herbicide transformation products.
