Quality Control

Our S-Methyl-Methylparathion is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets exacting standards for research and synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, related substances, and residual solvents to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. For long-term stability, storage at controlled room temperature (15-25°C) is recommended. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
