How should glycerol (CAS: 56-81-5) be stored?

Glycerol (CAS: 56-81-5) should be stored in a cool, dry, and well-ventilated area to maintain its chemical stability. It is hygroscopic, so exposure to humidity can lead to moisture absorption, affecting quality and purity. Storage conditions should avoid direct light, as UV exposure may degrade the compound over time. Glycerol is typically kept in sealed, airtight containers made of materials like glass or plastic to prevent contamination and evaporation. The ideal temperature range is between 15°C and 25°C, with humidity levels below 60% to ensure optimal shelf life. Freezing should be avoided, as it may alter the physical properties of glycerol. When stored correctly, glycerol remains stable for extended periods. Proper storage is essential to preserve its functionality and safety, particularly in industrial and pharmaceutical settings. The CAS number 56-81-5 is important for identifying storage guidelines in chemical databases. Always check the manufacturer’s specifications for additional precautions, such as avoiding incompatible substances or ensuring proper labeling.
