Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong bases and oxidizing agents.
