Quality Control

Our Dilongifolylborane is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay by NMR and impurity profiling, to meet the exacting standards required for advanced synthetic applications. A Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry place at 2-8°C. This material is hygroscopic (moisture-sensitive) and easily oxidized; containers must be kept sealed and handled under inert conditions to maintain purity and reactivity.
