Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under conditions that minimize exposure to ambient light and humidity to maintain stability and purity.
