Chemical Name: Isobutyraldehyde
Chemical Formula: C4H8O
Appearance: Clear, colorless liquid
Odor: Pungent, suffocating smell
Common Uses: Solvent, chemical intermediate, involved in the production of plastics, resins, and pharmaceuticals
Molecular Weight: 72.11 g/mol
Acute Health Risks: Irritation to eyes, skin, and respiratory system, potential central nervous system effects if inhaled
Flammability: Highly flammable liquid and vapor
Chronic Exposure: Risk of skin dryness and cracking, dizziness, or headache with prolonged inhalation
Environmental Risk: Harmful to aquatic life with long-lasting effects
Main Component: Isobutyraldehyde (concentration close to pure in industrial settings)
Additives or Impurities: Trace organics possible based on manufacturing source, but refinement usually keeps these minimal
Inhalation: Remove victim to fresh air, keep at rest, seek medical attention if symptoms persist
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, get medical advice if irritation persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, seek medical help if discomfort continues
Ingestion: Do not induce vomiting, rinse mouth, get medical support immediately
Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide
Unsuitable Extinguishing Media: Do not use water jet as it may spread fire
Special Hazards: Releases toxic fumes including carbon monoxide and formaldehyde on burning
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid breathing vapors
Environmental Precautions: Prevent spillage from entering drains or waterways
Clean-up Methods: Use inert absorbent material, collect in closed containers, wash spill area with plenty of water to reduce vapor hazards
Handling: Handle in well-ventilated spaces, avoid all sources of ignition, use spark-proof tools
Storage: Keep containers tightly closed in a cool, dry, well-ventilated place, store away from oxidizing agents and incompatible substances
Additional Insight: Training in chemical handling increases safety and reduces accidents—basic protocols actually make a difference
Occupational Exposure Limits: Maintain air levels below recommended standards set by regulatory bodies
Engineering Controls: Use fume hoods or local exhaust ventilation
Personal Protective Equipment: Protective gloves (nitrile or neoprene), safety goggles, flame-resistant lab coats, and, in case of high vapor risk, respirators
Operational Practices: Regular equipment checks and air monitoring allow teams to respond before levels become hazardous
Boiling Point: About 63°C (145°F)
Melting Point: -65°C (-85°F)
Flash Point: -18°C (0°F)
Vapor Pressure: Relatively high, which underscores need for proper containment
Solubility: Moderately soluble in water, miscible with many organic solvents
Density: 0.8 g/cm³
Physical State: Liquid
Stability: Chemically stable under recommended storage conditions
Hazardous Reactions: Risk of violent reaction with strong oxidizers, acids, or alkalis
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, formaldehyde
Incompatibilities: Avoid contact with acid chlorides, strong acids, alkalis, and oxidizing materials
Acute Toxicity: Irritation of respiratory system, skin, and eyes with repeated or high exposure
Inhalation Effects: Dizziness, headache, possible unconsciousness with significant exposure
Ingestion Effects: Nausea, vomiting, abdominal pain, central nervous system effects possible
Skin/Eye Effects: Redness, discomfort, potential chemical burns with extended contact
Chronic Risks: Prolonged or repeated exposure may cause dermatitis
Aquatic Toxicity: Harmful to aquatic organisms, even at low concentrations
Persistence and Degradability: Can degrade in air and water but does not break down quickly in all environmental conditions
Bioaccumulation Potential: Not expected to bioaccumulate extensively, but impact on aquatic environments remains concerning
Soil Impact: Volatilizes rapidly, but can persist if released into soils without good aeration
Disposal Methods: Incinerate in a chemical incinerator equipped with afterburner and scrubber, or send to licensed waste facility
Container Disposal: Triple rinse and puncture container before recycling or disposal
Resource Recovery: Consider solvent recovery wherever permitted by law to reduce waste
Proper Shipping Name: Isobutyraldehyde
Hazard Class: Flammable liquid
Packing Group: II
Label Required: Flammable liquid (red diamond), comply with transport-specific rules for both road and sea shipping
Special Precautions: Isolate from food and feedstuffs, restrict transport through densely populated areas
Occupational Safety Standards: Subject to chemical safety, worker right-to-know, and hazardous substance control regulations in many jurisdictions
Environmental Controls: Must not be released into the environment without proper controls, specific restrictions on emissions apply
Workplace Controls: Employers monitor exposure, train workers, and maintain documentation as required under chemical handling laws
Reporting Requirements: Facilities reporting use or storage may have mandatory registration or inventory disclosures based on national standards
