Quality Control

Our production of 13-[2-[2-[2-(2-Hydroxyethoxy)Ethoxy]Ethoxy]Ethoxy]-3,6,9,12,14,17,20,23-Octaoxa-13-Borapentacosane-1,25-Diol adheres to stringent quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes.

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 after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
