Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Keep away from heat, sparks, and open flames. Due to its light-sensitive and easily oxidized nature, prolonged exposure to air and light should be avoided.
