Quality Control

Our Tetraboron Pentaoxide Tetrahydroxide Ion(-2) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. While specific grades are available, all materials undergo rigorous analytical testing. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored in a cool, dry place with minimal exposure to atmospheric humidity. For long-term storage, consider the use of a desiccator or inert atmosphere. Recommended storage temperature is 15-25°C.
