Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 2-8°C (refrigerated) or as specified for specific grades. This product is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) to maximize shelf life. Due to its high volatility, keep containers tightly sealed when not in use.
