Description

Phorate-Oxon is a key organophosphate compound and the primary oxygen analog metabolite of the insecticide Phorate. This compound is of significant importance in analytical chemistry and environmental science for the study of pesticide degradation, metabolic pathways, and residue analysis. It serves as a critical reference standard and intermediate for researchers and manufacturers in the agrochemical, analytical, and regulatory sectors requiring precise chemical markers for quality control and environmental monitoring.

Application

• Analytical Reference Standard: Primary use as a certified high-purity standard for calibrating equipment and quantifying Phorate and its metabolites in environmental and biological samples via GC-MS, LC-MS, and HPLC.
• Environmental Fate Studies: Essential for researching the degradation, transformation, and persistence of organophosphate pesticides in soil and water systems.
• Metabolic Pathway Research: Used in toxicological studies to understand the biotransformation and enzymatic oxidation (desulfuration) of Phorate in plants, insects, and mammals.
• Agrochemical Intermediate: Acts as a synthetic precursor or degradation model compound in the development and testing of new pesticide formulations and safer alternatives.
• Regulatory Compliance & Residue Analysis: Critical for laboratories performing compliance testing for food safety (e.g., maximum residue limits - MRLs) and environmental regulations.
• Quality Control (QC) in Manufacturing: Employed by agrochemical producers to monitor the quality, purity, and consistency of Phorate production batches and to identify impurities.

Quality Control

Our Phorate-Oxon is manufactured and handled under strict quality protocols to ensure high purity and batch-to-batch consistency, suitable for sensitive analytical applications. Each lot undergoes comprehensive analysis including identification, assay, and impurity profiling. A detailed Certificate of Analysis (COA) is provided, documenting purity (typically ≥95% by HPLC), identity confirmation (by IR, NMR), and relevant physical data. We support compliance with ISO 9001 quality management principles, and our standards are tailored for research and regulatory use.

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). Keep away from strong bases and incompatible materials such as organic solvents. For long-term stability, consider storage under an inert atmosphere.
