Quality Control

Our Phosphenothious Chloride is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including purity assay and impurity profiling, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing specific results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and organic solvents.
