Quality Control

Our P,p-Bisaziridinyl Thiophosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, purity verification, and impurity profiling, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to strong bases and organic solvents, and because it is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
