Quality Control

Our Phenyl Dihydrogen Orthoborate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, purity profiling, and identification, to ensure it meets the high standards required for advanced synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with minimal exposure to humidity. Recommended storage temperature is 2-8°C for long-term stability. Handle and store under an inert atmosphere (e.g., nitrogen or argon) for optimal preservation of quality.
