Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to maintain stability and prevent degradation. Keep away from strong oxidizing agents and heat sources.
