Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and contains fluoride/strong alkali; ensure containers are kept tightly sealed to prevent moisture absorption and degradation. Keep away from strong acids and incompatible materials.
