Quality Control

Our Tri-n-Propylboron is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency suitable for sensitive synthetic applications. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by NMR or titration), color, and moisture content is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area, away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, the container must be kept tightly sealed and handled with appropriate precautions to prevent exposure to air and moisture. Recommended storage temperature is 2-8°C for long-term stability.
