Quality Control

Our Bis(p-Tolyl)Dibromotellurium(IV) is produced and handled under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including NMR (1H, 13C) and elemental analysis, to confirm identity and composition. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Due to its moisture-sensitive and easily oxidized nature, the container should be kept sealed and allowed to reach ambient temperature before opening to minimize condensation. Recommended long-term storage temperature is 2-8°C.
