Quality Control

Our 1,1-Dioxido-2,3-Dihydro-3-Thienyl Diphenyl Phosphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment, ensuring full traceability and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the potential sensitivity of the phosphate ester and sulfone groups, prolonged exposure to high humidity or extreme temperatures should be avoided.
