Quality Control

Our Tributyl Borate-10B is produced and handled under strict quality protocols to ensure isotopic and chemical purity. Each batch is analyzed to confirm the 98 Atom % 10B enrichment level and overall chemical specification. Certificates of Analysis (COA) detailing isotopic ratio (by NMR or MS), chemical assay, and impurity profiles are provided. We adhere to cGMP principles where applicable for research and pharmaceutical-grade materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and must be handled under a dry, inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain purity. Keep away from strong oxidizers and acids.
