Quality Control

Our Diethyl Selenide is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including GC and NMR, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing specific results for identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flame. Recommended long-term storage temperature is 2-8°C.
