Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve stability and prevent degradation. Keep away from strong oxidizing agents.
