Quality Control

Our Phosphorus Dimer is produced and handled under stringent conditions to ensure the highest purity and consistency required for research and industrial applications. Quality is verified through advanced analytical techniques including gas chromatography-mass spectrometry (GC-MS) and spectroscopic methods. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming key parameters such as purity and isotopic composition. We adhere to a rigorous quality management system to guarantee batch-to-batch reliability.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature, this material must be stored under an inert atmosphere (e.g., argon or nitrogen) in a certified pressure vessel at room temperature (15-25°C). Store away from heat, ignition sources, and oxidizing agents. The container must be kept in a well-ventilated, cool, and dry place. Handle and store only in equipment designed for high-pressure, reactive gases.
