Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation and moisture uptake. Keep away from heat and incompatible materials.
