Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and polymerization.
