Quality Control

Our (2-Ethoxy-3-Methylphenyl)Boronic Acid is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, typically exceeding 97% (HPLC). Each lot is characterized by NMR (1H, 13C, 11B), HPLC, and mass spectrometry to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C. Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) to prevent moisture absorption and decomposition. Keep away from heat and incompatible materials.
