Quality Control

Our Trihexadecylphosphine is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing purity, assay, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
