Quality Control

Our 4,4,5,5-Tetramethyl-2-(4-(o-Tolyloxymethyl)Phenyl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including NMR, HPLC, and GC analysis, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 heat, sparks, and open flame.
