Quality Control

Our Dibromotetrakis(Pyridine)Nickel is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay and identification by spectroscopic methods. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee compliance with your research and process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and may require storage under an inert atmosphere for long-term stability.
