Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider using an inert atmosphere (e.g., nitrogen blanket) to maintain product integrity. Keep away from strong oxidizing agents.
