Quality Control

Our Hexaethyldisilane is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) and nuclear magnetic resonance (NMR) spectroscopy, to verify identity and assay. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended long-term storage temperature is 2-8°C.
