Quality Control

Our Selenide CAS NO 22541-48-6 is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including ICP-MS and titration methods, to verify composition and limit trace metallic impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent degradation. Isolate from strong acids and oxidizing agents.
