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). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed after opening to minimize exposure to moisture and prevent evaporation. Keep away from heat, sparks, and open flame.
