Description

Fenamiphos Sulfone is a key organophosphate metabolite and degradation product of the nematicide fenamiphos. This compound is of significant importance for analytical reference, environmental monitoring, and toxicological studies. It is primarily required by agrochemical manufacturers, analytical laboratories, and regulatory bodies for residue analysis, method validation, and compliance testing.

Application

• Analytical Reference Standard for the quantification of fenamiphos and its metabolites in environmental and agricultural samples.
• Metabolite Standard in toxicology and metabolism studies to understand the degradation pathway of fenamiphos.
• Quality Control (QC) Material for the calibration of HPLC, GC-MS, and LC-MS/MS systems in analytical laboratories.
• Environmental Fate Studies to track and assess the persistence and transformation of fenamiphos in soil and water.
• Regulatory Compliance Testing to ensure adherence to maximum residue limits (MRLs) in food and water safety programs.
• Research and Development in the synthesis of new agrochemical compounds or degradation inhibitors.

Quality Control

Our Fenamiphos Sulfone is produced and handled under strict quality management protocols to ensure high purity and batch-to-batch consistency, suitable for analytical and research purposes. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We support compliance with global standards for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, keep the container tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
