Quality Control

Our Tetrasilane (Si4H10) is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as purity and impurity profiles. For specific applications requiring electronic or semiconductor grades, tailored specifications and additional testing are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area, away from heat, ignition sources, and incompatible materials such as strong oxidizers. Due to its highly volatile and easily oxidized nature, containers must be kept sealed and handled with appropriate precautions to prevent pressure build-up and decomposition.
