Chemical Name: Diisobutylamine
Common Synonyms: DIBA, 2-methylpropyl(isobutyl)amine
Chemical Formula: C8H19N
Appearance: Colorless to pale yellow liquid with a strong, ammonia-like odor
Uses: Organic synthesis, corrosion inhibitors, rubber processing, and surfactant manufacturing
GHS Classification: Flammable liquid, Acute toxicity (oral, dermal, inhalation), Skin and eye irritant
Main Risks: Flammable vapors, respiratory and skin irritation, potential neurotoxicity on heavy exposure
Hazard Statements: Causes burns, harmful if swallowed or inhaled, highly flammable
Signal Words: Danger or Warning (depending on concentration and quantity)
Ingredient: Diisobutylamine
Chemical Purity: Typically above 98% in industrial grades
Impurities: Trace organic amines and water
Inhalation: Move affected person to fresh air and keep them at rest; support breathing if struggling
Skin Contact: Remove contaminated clothing, flush skin with running water and soap for at least 15 minutes
Eye Contact: Rinse eyes under running water for several minutes; do not rub the eyes
Ingestion: Do not induce vomiting; rinse mouth with water and seek professional medical help quickly
General Advice: Immediate medical review for significant exposure or symptoms like breathing trouble
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide
Fire Hazards: Vapors may form explosive mixtures with air and can travel long distances, sparking fires away from source
Specific Dangers: May emit toxic fumes of nitrogen oxides under combustion
Protective Equipment: Wear self-contained breathing apparatus and full protective gear; keep containers cool with water spray
Personal Safety: Evacuate area and fight fire from a distance, avoiding inhalation of vapors or smoke
Personal Protection: Use chemical-resistant gloves, splash-proof goggles, long sleeves, and respiratory protection if ventilation is poor
Spill Management: Stop leak if safe, absorb with inert material like sand or vermiculite, avoid direct contact
Environmental Precautions: Block entry to drains or waterways, prevent further leakage or spillage
Cleanup: Collect and dispose of absorbed material in compliance with local waste guidelines
Area Ventilation: Air out contaminated area thoroughly after cleanup
Safe Handling: Work in well-ventilated areas, use spark-proof tools, avoid inhaling vapors, protect skin and eyes
Storage Conditions: Store in tightly closed, corrosion-resistant containers away from sources of ignition
Incompatibilities: Strong oxidizing agents, acids, acid chlorides
Precautionary Advice: Label storage areas clearly, keep out of reach of children and untrained individuals
Temperature Storage Range: Cool, dry, and well-ventilated spaces preferred
Ventilation: Use local exhaust and general ventilation to control airborne levels
Personal Protective Equipment: Impermeable gloves, chemical-resistant goggles, lab coats or aprons, face shields in splash zones
Respiratory Protection: Use respirators suitable for organic vapors if exposure limits may be exceeded
Hygiene Measures: Wash hands and exposed skin before breaks and on leaving work; no eating or drinking in work area
Occupational Limits: Set by local workplace regulations where available, adherence is necessary for safety
Molecular Weight: 129.25 g/mol
Boiling Point: Ranges between 129–133 °C
Melting Point: Below -75 °C
Flash Point: 28 °C (open cup, varies slightly by source)
Vapor Pressure: Moderate, can contribute to airborne concentrations indoors
Solubility: Limited solubility in water, readily soluble in many organic solvents
Odor Threshold: Detectable at low concentrations, pungent smell
Density: About 0.76 g/mL at 20 °C
Physical State: Liquid at room temperature
Appearance: Clear to pale straw-colored
Chemical Stability: Stable under standard conditions if stored properly
Reactive Conditions: Reacts strongly with oxidizing agents and acids
Hazardous Decomposition Products: Ammonia, nitrogen oxides
Possibility of Hazardous Reactions: Polymerization not expected, but exothermic reactions possible with incompatible chemicals
Storage Concerns: Keep away from heat, sparks, open flames, and sunlight
Routes of Exposure: Inhalation, skin absorption, ingestion, eye contact
Acute Toxicity: Harmful by all exposure routes; oral LD50 in rats reported around 750 mg/kg
Effects of Short-Term Exposure: Irritation of eyes, nose, throat and skin; coughing, dizziness, headaches possible
Chronic Effects: Prolonged or repeated exposure risks skin sensitization and possible liver or kidney damage
Carcinogenicity: Not classified as carcinogenic by IARC or NTP
Sensitization: May cause allergic skin reactions with repeated contact
Aquatic Toxicity: Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradation: Not readily biodegradable, tends to linger in soils and waterways
Bioaccumulation Potential: Low potential based on molecular structure, but environmental monitoring is critical
Environmental Precautions: Never pour down drains; spills near waterways require immediate response
Mobility in Soil: Moderate, can leach into groundwater if large spills go unmanaged
Waste Treatment: Treat as hazardous waste, follow local and national requirements
Container Disposal: Empty drums or containers must not be reused and should be punctured and sent for specialized collection
Waste Disposal: Send to licensed waste disposal contractor; incineration preferred if allowed
Environmental Protection: Avoid release into sewers, surface water, or soil
Shipping Name: Consult local transport regulations for specific classification
Hazard Class: Flammable Liquid
Packing Group: Usually II or III depending on volume and concentration
Precautions: Label shipments clearly, secure containers, keep away from foodstuffs
Regulatory Notes: Transport only with properly trained personnel; emergency response plan in transit recommended
Chemical Inventories: Listed on major national and regional inventories such as TSCA, REACH, AICS
Worker Protection Laws: Occupational exposure limits and guidelines set by OSHA, ACGIH, or other national agencies
Labeling Requirements: GHS-compliant hazard labeling; warning pictograms mandatory
Environmental Regulation: Discharges are regulated under water and waste laws; reporting required for significant releases
Community Safety: Facilities often required to perform and document hazard risk assessments under safety planning statutes
Ongoing Review: Regulatory status can shift due to new research, keep up with changes to workplace guidelines and environmental controls
