Quality Control

Our 1,4-Bis(Dichlorophosphino)Butane is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurity profiles 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 under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after each use to exclude moisture and air. Recommended storage temperature is 2-8°C for long-term stability.
