Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive and moisture-sensitive nature, this material must be stored under an inert atmosphere (argon or nitrogen) at temperatures recommended for the specific solvent formulation (typically between 2°C and 25°C). The container should be kept in a cool, dry, well-ventilated area away from incompatible materials such as oxidizing agents, acids, and water.
