Quality Control

Our Dichloro(Propadienyl)Phosphine is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR and GC/HPLC analysis, to verify identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure full traceability and compliance with your research or production requirements.

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 place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and incompatible materials.
