Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C. This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability and prevent degradation. Keep away from heat, sparks, and open flame.
