Product Profile
Chemical Structure and Properties
Molecular Formula: C₈H₁₂N₄
Structural Formula: (CH₃)₂C(CN)–N=N–C(CN)(CH₃)₂
Appearance: White to pale yellow crystalline powder
Melting Point: 105–110°C
Density: 1.0 g/cm³
Solubility: Slightly soluble in water; soluble in organic solvents such as ethanol, acetone, and ether
Chemical Properties:
Organic azo compound with a –N=N– functional group
Decomposes thermally to release nitrogen gas, generating free radicals
Stable under standard conditions but sensitive to heat, friction, and shock
Industrial Applications
Polymerization Initiator: Widely used as a radical initiator in polymerization of acrylics, styrenics, and vinyl monomers
Plastic and Rubber Manufacturing: Initiates crosslinking reactions in plastics and synthetic rubber
Specialty Chemical Synthesis: Used as a reagent in organic synthesis for free radical reactions
Laboratory Use: Commonly employed in research for radical polymerizations and as a source of radicals
Safety and Toxicology
Health Hazards: May cause skin and eye irritation; inhalation of dust can irritate respiratory tract
Fire & Explosion Risk: Explosive under heat or friction; emits toxic fumes upon decomposition
Protective Measures: Handle in well-ventilated areas; use gloves, safety goggles, and avoid heat sources
Environmental and Regulatory Considerations
Environmental Impact: Avoid release into waterways; biodegradable under aerobic conditions is limited
Regulatory Compliance: Classified as hazardous under GHS; transport as Class 4.1 (flammable solid)
Case Studies / Application Insights
Polymer Industry: Efficiently initiates radical polymerizations, improving molecular weight control and polymer uniformity
Alternative Comparison: Compared to benzoyl peroxide, AIBN provides a cleaner radical source with fewer by-products in specific polymerizations
