Quality Control

Our 2-Methoxy-4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl Acetate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, NMR, and GC to confirm identity, potency, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with every shipment and are available upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
