Chemical Name: 4-Heptanone
Chemical Formula: C7H14O
Synonyms: Heptan-4-one, Dipropyl ketone
CAS Number: 123-19-3
Hazard Classification: Flammable liquid and vapor, Harmful if swallowed, Harmful if inhaled, Causes serious eye irritation
GHS Label Elements: Flame, Exclamation mark
Primary Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Eye and respiratory tract irritation, dizziness, headache
Chronic Effects: Prolonged or repeated exposure may lead to effects on the central nervous system
Main Ingredient: 4-Heptanone (greater than 98%)
Impurities: Trace ketones, alkanes (variable, depend on source; often not quantified)
Inhalation: Remove person to fresh air, support breathing, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, use lotion if irritation develops
Eye Contact: Rinse immediately with gentle running water for at least 15 minutes, remove contact lenses if present, consult a medical professional if irritation continues
Ingestion: Rinse mouth, seek immediate medical advice, do not force vomiting
Suitable Extinguishing Media: Foam, dry powder, carbon dioxide, water spray (avoid direct stream which may spread fire)
Specific Hazards: Produces toxic fumes of carbon monoxide and carbon dioxide during combustion, vapor may form explosive mixture with air
Protective Equipment: Full protective gear including self-contained breathing apparatus recommended for responders
Personal Precautions: Use chemical-resistant gloves and goggles, ventilate area, avoid breathing vapors
Environmental Precautions: Prevent further leakage or spillage if safe, block entry to drains or waterways
Containment and Clean Up: Absorb with inert absorbent, collect and dispose of according to local waste regulations, wash spill site after cleanup
Handling: Use in a well-ventilated area, keep container tightly closed, avoid all sources of ignition, handle with equipment that resists static electricity
Storage: Store away from heat, sparks, and open flame, keep in a cool, dry, well-ventilated place in original container, segregate from incompatible substances like oxidizers and acids
Occupational Exposure Limits: No specific guidelines in the US, refer to guidelines for similar ketones
Engineering Controls: Use exhaust ventilation or other engineering controls to keep airborne levels below recommended exposure limits
Personal Protection: Gloves resistant to chemicals, safety goggles or full-face shield, protective clothing, NIOSH-approved organic vapor respirators if ventilation is inadequate
Appearance: Clear, colorless to faintly yellow liquid
Odor: Sweet, acetone-like scent
Boiling Point: Around 151-153°C
Melting Point: -48°C
Flash Point: Approximately 42°C (closed cup)
Solubility in Water: Slightly soluble
Vapor Pressure: Moderate at room temperature
Density: About 0.818 g/cm³
Stability: Stable under recommended storage conditions
Conditions to Avoid: High temperature, ignition sources, static discharge
Incompatible Materials: Strong acids, oxidizing agents, reducing agents
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, possibly other toxic substances upon burning
Acute Toxicity: Moderately toxic by ingestion, inhalation may depress the central nervous system, prolonged exposure amplifies risk
Skin and Eye Contact: Irritation likely if direct prolonged contact, possible risk of corneal injury with eye exposure
Sensitization: Not known to cause skin sensitization in humans
Others: No evidence of carcinogenicity or mutagenicity reported in current literature, but specific studies are limited
Aquatic Toxicity: Harmful to aquatic life if released in significant quantity, bioaccumulation potential considered low
Persistence and Degradability: Expected to be biodegradable, breaks down under aerobic conditions
Mobility: High mobility in soil predicted due to molecular weight and water solubility
Other Risks: Spills increase potential for groundwater contamination, direct harm to fish or aquatic insects possible if concentration is high
Methods: Collect in sealed containers for disposal by approved hazardous waste facilities, avoid incineration unless permitted, never pour into drains or open environment
Precautions: Handle waste with gloves, goggles, and in ventilated areas, decontaminate any tools or containers used with suitable solvents
Proper Shipping Name: Flammable liquid, n.o.s. (contains 4-Heptanone)
UN Number: UN 1993
Hazard Class: 3 (Flammable liquid)
Packing Group: III
Transportation Precautions: Secure tightly, use secondary containment, keep away from incompatible substances during transit
Applicable Laws: Subject to regional and national chemical inventory registration (US TSCA, EU REACH, etc.)
Classification: Classified as hazardous under GHS criteria due to flammable and irritant qualities
Labeling Requirements: Flammable liquid label, health hazard statement required for workplace containers
