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 product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation and polymerization. Keep away from heat, open flames, and sources of ignition. For long-term storage, consider refrigeration at 2-8°C under inert conditions.
