Quality Control

Our Butylphosphonothioic Dichloride is manufactured under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids and organic solvents; it must be kept under an inert atmosphere (e.g., nitrogen or argon) and isolated from incompatible materials.
