Quality Control

Our Bis(Methylcyclopentadienyl)Zirconium Dichloride is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including NMR, elemental analysis, and chromatography, to confirm identity and purity. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, this material should be handled and stored under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Recommended long-term storage temperature is 2-8°C.
