Quality Control

Our 2-(2,3-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request to support your quality assurance and regulatory documentation needs.

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, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Recommended long-term storage temperature is 2-8°C.
