Quality Control

Our Diphenylphosphine Selenide 95% is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets the declared specification of 95% minimum purity. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C to minimize degradation. Due to its hygroscopic and easily oxidized nature, containers must be kept sealed and allowed to reach room temperature before opening to prevent moisture ingress.
