Quality Control

Every batch of this advanced material is produced and analyzed under strict inert atmosphere conditions to prevent oxidation. Quality is assured through comprehensive analytical techniques including NMR (1H, 13C), HPLC, and elemental analysis to confirm structural integrity and high purity, typically >98%. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting batch-specific results.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at 2-8°C under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. This compound is hygroscopic (moisture-sensitive) and easily oxidized; containers must be sealed immediately after use to minimize exposure to air and moisture.
