Description

Cloransulam-Desethyl is a key metabolite and analytical reference standard of the herbicide cloransulam-methyl, identified by CAS NO 171297-30-6. This compound is essential for environmental fate studies, residue analysis, and the development of robust analytical methods in agricultural science. It is primarily required by agrochemical manufacturers, regulatory testing laboratories, and research institutions focused on herbicide metabolism and environmental safety.

Application

• Analytical Reference Standard: Primary use as a high-purity standard for calibrating equipment and quantifying residues in environmental and crop samples via HPLC or LC-MS/MS.
• Metabolism and Degradation Studies: Critical for researching the environmental fate and metabolic pathways of the parent herbicide cloransulam-methyl in soil and plants.
• Regulatory Compliance and Residue Testing: Used by testing labs to validate analytical methods and ensure compliance with maximum residue limits (MRLs) set by global agencies like the EPA and EFSA.
• Agrochemical Research & Development: Serves as a key intermediate or marker in the development and improvement of sulfonamide herbicide formulations.
• Quality Control for Manufacturing: Employed in the quality assurance processes of agrochemical producers to monitor impurity profiles and ensure batch consistency.
• Toxicological and Ecotoxicological Assessments: Used in studies to evaluate the potential impact and safety profile of herbicide degradation products.

Quality Control

Our Cloransulam-Desethyl is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, MS), to ensure it meets the high standards required for analytical and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). The material is hygroscopic (moisture-sensitive); ensure the container is sealed under inert atmosphere after opening to maintain stability and purity.
