Quality Control

Our Diethylborinic Acid Trimethylsilyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle and store the product under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent decomposition. Ideal storage temperature is between 2°C and 8°C for long-term stability.
