Quality Control

Our Triisobutylborane is produced under stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling via NMR and GC, to ensure high purity and consistent performance. Certificates of Analysis (COA) documenting exact specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material must be stored under an inert atmosphere (nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Isolate from strong oxidizers, acids, and moisture.
