As an accredited 2,2'-Azobisisobutyronitrile factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | 2,2'-Azobisisobutyronitrile, 500g: Supplied in a sealed, amber glass bottle with tamper-evident cap, labeled with hazard and safety information. |
| Shipping | 2,2'-Azobisisobutyronitrile (AIBN) should be shipped as a hazardous material, specifically as a flammable solid (UN 3234, Class 4.1). It must be packed in tightly sealed containers, protected from heat, sparks, and direct sunlight, with appropriate labeling and documentation, in compliance with relevant shipping regulations (IATA, IMDG, DOT). |
| Storage | 2,2'-Azobisisobutyronitrile (AIBN) should be stored in a tightly closed container in a cool, dry, and well-ventilated area, away from heat, sparks, flame, and direct sunlight. Store at temperatures below 40°C and protect from moisture and incompatible substances such as strong acids and oxidizing agents. Avoid friction, shock, and contamination, as AIBN is sensitive and may decompose explosively. |
