Quality Control

Our Tris(4-Bromo-2,3,5,6-Tetramethylphenyl)Borane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. We adhere to relevant industry standards, and specifications can be tailored to meet specific research or production requirements.

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 handled in a controlled environment to maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
