Quality Control

Our Tetraethylammonium Bis[1,2-Benzenediolato(2-)-O,O']-Borate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity, identity, and lot-to-lot consistency. Standard quality checks include assay (by NMR or titration), identification (IR, NMR), and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support cGMP and ISO 9001 standards for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon or nitrogen) when possible to prevent decomposition. Keep the container tightly sealed in a desiccator for long-term storage.
