Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is between 2°C and 8°C for extended stability, although short-term storage at controlled room temperature (15-25°C) is acceptable. Keep container tightly sealed when not in use to minimize moisture absorption and volatilization.
