Azobisisobutyronitrile (AIBN) is a vital chemical initiator widely used in polymerization and organic synthesis. While its efficacy is well-established, its nature as a thermally sensitive compound necessitates strict adherence to safety protocols. NINGBO INNO PHARMCHEM CO.,LTD. not only supplies high-quality AIBN but also emphasizes the importance of its safe handling and storage to ensure the well-being of professionals and the integrity of the chemical.

AIBN is classified as a flammable solid and is known for its thermal instability. The key hazard associated with AIBN is its tendency to decompose exothermically when exposed to heat, potentially leading to rapid pressure buildup and explosion, especially in confined spaces or at elevated temperatures. While safer than some organic peroxides, it is still considered an explosive compound that can decompose above 65°C. Therefore, maintaining controlled storage temperatures, ideally between 2°C and 8°C, or even lower for long-term storage (below -20°C), is crucial to prevent self-accelerating decomposition.

When handling AIBN, professionals must employ appropriate personal protective equipment (PPE). This includes chemical-resistant gloves, safety goggles or a face shield, and respiratory protection, such as a dust mask, to prevent inhalation of fine particles. Work areas should be well-ventilated, and sources of ignition—including open flames, sparks, and hot surfaces—must be strictly eliminated. It is also important to avoid contact with incompatible materials, such as strong oxidizing agents, acids, acetone, and certain metals, which can trigger hazardous reactions or accelerate decomposition.

Proper storage involves keeping AIBN in its original, tightly sealed container, preferably in a cool, dark, and dry location. Avoid storing it near flammable materials or in direct sunlight. For larger quantities, specialized storage facilities that can maintain consistent low temperatures are recommended. When transporting AIBN, it must be kept away from heat and potential sources of ignition, adhering to all relevant transport regulations for hazardous materials.

For those looking to buy AIBN, it is imperative to source from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD., who provide comprehensive safety data sheets (SDS) and product information. Adhering to these guidelines not only ensures personal safety but also preserves the quality and reactivity of the AIBN, guaranteeing optimal performance in your applications. Responsible handling and storage are integral to successfully utilizing this powerful chemical initiator.
