Quality Control

Our Hafnium Chloride Tetrahydrofuran Complex (1:2) is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including Inductively Coupled Plasma (ICP) for metal assay, Karl Fischer titration for moisture, and spectroscopic methods for identity confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon or nitrogen) to prevent degradation. Keep away from strong acids and incompatible organic solvents.
