Diethanolamine should be stored in a cool, dry place, away from direct sunlight and incompatible substances. It is recommended to use airtight containers to prevent moisture absorption and contamination. Due to its chemical neutrality, it does not react aggressively with most laboratory materials, but it is still important to handle it with care. Proper labeling of containers is essential to ensure safe handling and prevent accidental exposure. In laboratory settings, it is advisable to use appropriate personal protective equipment when handling DEA, especially during preparation and storage. Regular inspection of storage conditions ensures the integrity and effectiveness of the material for analytical applications.
