Quality Control

Every batch of 4,5-Dimethyl-2-Phenyl-1,3,2-Dioxaborolane is manufactured and tested under strict quality management protocols to ensure it meets the high standards required for sensitive synthetic applications. Our quality assurance includes comprehensive analytical testing via NMR, HPLC, and GC-MS. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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) after opening to prevent moisture absorption and degradation.
