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 strictly light-sensitive (protect from all light exposure) to prevent premature degradation of its photochromic function. For long-term storage, consider an inert atmosphere to minimize potential oxidation.
