Quality Control

Our Trimethyl Borate-11B is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high isotopic enrichment. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic purity (11B enrichment), chemical purity, and impurity profile. We support research and industrial standards, and specifications can be tailored to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, and open flames.
