Quality Control

Our 4,4,5,5-Tetramethyl-2-(2-Methyl-4-(Methylsulfonyl)Phenyl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and structural integrity. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee compliance with your research and development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Keep away from incompatible materials.
