Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain stability and purity. Keep away from strong oxidizing agents.
