Quality Control

Our Tetramethylenebis[Bis(2-Cyanoethyl)Phosphine] is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including chromatographic purity analysis and structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under an inert atmosphere for long-term stability.
