Quality Control

Our Dichloro(1-Methylpropadienyl)Phosphine is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, GC, and titration methods, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from heat, sparks, and open flame.
