As an accredited Acetic anhydride factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | 1-liter amber glass bottle, sealed with a chemical-resistant cap, labeled "Acetic Anhydride" with hazard symbols and handling instructions. |
| Shipping | Acetic anhydride must be shipped in tightly sealed containers made of compatible, non-reactive materials. It is classified as a hazardous material (flammable and corrosive, UN1715) and requires labeling, proper documentation, and compliance with local, national, and international transport regulations. Avoid shipping with incompatible substances like water, alcohols, and strong oxidizers. |
| Storage | Acetic anhydride should be stored in a cool, dry, and well-ventilated area, away from moisture, heat sources, and incompatible materials such as water, alcohols, and strong oxidizers. Keep the chemical in tightly-sealed containers, ideally made of glass or stainless steel. Store in a flammable liquids cabinet and ensure proper labeling. Avoid exposure to air to prevent hydrolysis. |
