Quality Control

Our production of Phosphorodifluoridous Acid, Ethylene Ester adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analysis, including assay by NMR and GC, purity verification, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with REACH and other global regulatory frameworks.

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 hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Isolate from strong alkalis and incompatible materials.
