Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen) to preserve stability and organoleptic properties. Keep away from strong oxidizing agents.
