Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
