Name: N,N-Dimethylcyclohexylamine Chemical Formula: C8H17N CAS Number: 98-94-2 Appearance: Clear to pale yellow liquid with a strong amine-like odor Industrial Use: Typically used in the manufacture of polyurethane foam, corrosion inhibitors, and as a catalyst in organic synthesis
GHS Classification: Flammable liquid, Acute toxicity (oral, dermal, inhalation), Skin and eye irritation Hazard Pictograms: Flame, Exclamation mark, Health hazard Label Elements: Warning regarding vapor and liquid flammability, toxicity, and potential for skin and respiratory irritation Main Dangers: Short-term exposure can irritate eyes, nose, and throat; can cause dizziness and drowsiness; skin contact may lead to burns Chronic Risks: Long-term handling without protective gear may cause dermatitis and possible central nervous system effects
Chemical Content: Contains a minimum 99% N,N-Dimethylcyclohexylamine by weight Impurities: Trace amounts of related amines may be present due to production processes
Inhalation: Remove person to fresh air; seek medical attention if symptoms persist Skin Contact: Remove contaminated clothing; wash skin thoroughly with soap and water; seek medical advice for irritation Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do; continue rinsing Ingestion: Rinse mouth; do not induce vomiting; seek medical attention immediately
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide; water spray may be used for cooling containers but not for extinguishing small fires Common Hazards: Fire may emit toxic fumes of nitrogen oxides and carbon monoxide Personal Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing Special Notes: Vapors heavier than air may travel to sources of ignition and flash back
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid breathing vapors Spill Management: Absorb with inert material such as sand or earth; dispose of contaminated material per local regulations Environmental Precautions: Prevent entry into drains, sewers, and waterways
Handling: Wear suitable protective clothing, gloves, and eye/face protection; keep away from heat, sparks, and open flames Storage: Store in tightly closed containers in a cool, well-ventilated area away from incompatible substances such as acids or oxidizing agents; keep away from direct sunlight Incompatibilities: Avoid contact with strong oxidizers and acids
Engineering Controls: Use local exhaust ventilation to prevent vapor build-up Personal Protection: Chemical-resistant gloves, safety goggles, flame-resistant lab coats, and, in case of insufficient ventilation, appropriate respiratory protection Workplace Monitoring: Regular checks for airborne concentration, especially in closed environments or during large-scale operations
Odor: Strong amine-like Boiling Point: Around 163–168°C Flash Point: Approximately 47°C (open cup) Solubility: Limited in water; mixes with organic solvents Vapor Pressure: Moderate Density: Roughly 0.86–0.87 g/cm³ Stability: Stable under recommended storage and handling conditions
Chemical Stability: Stable in closed containers under normal conditions Hazardous Reactions: Reacts with strong acids, oxidizing agents, and chlorinating agents; may form toxic or flammable fumes Decomposition: Product of combustion includes nitrogen oxides, carbon monoxide, and carbon dioxide
Acute Toxicity: Oral and inhalation routes cause moderate to high toxicity; skin absorption may also be harmful Symptoms of Exposure: Irritation to eyes, skin, and respiratory tract; prolonged exposure may result in headache, nausea, and confusion Long-term Effects: Chronic skin contact may cause dermatitis; repeated inhalation might contribute to respiratory issues
Aquatic Toxicity: Toxic to aquatic organisms at low concentrations Persistence: May not easily biodegrade in the environment Bioaccumulation: Potential to accumulate in aquatic life remains uncertain due to limited research Soil Impact: Spills or leaks can contaminate groundwater or soil if not promptly managed
Waste Disposal: Dispose as hazardous chemical waste in accordance with local and national regulations; avoid release to the environment Container Handling: Empty containers retain chemical; triple-rinse and dispose under hazardous waste protocol
UN Classification: Regulated as a flammable liquid Transport Hazards: Labels and documentation must indicate presence of flammable and toxic components; accidents or leaks require immediate reporting Precautions During Transport: Secure containers upright; avoid excessive heat, shock, and incompatible cargo
OSHA Status: Regulated as a hazardous chemical in the workplace GHS Compliance: Labeling, pictograms, and documentation required Environmental Law: Subject to local discharge and disposal regulations due to aquatic toxicity Workplace Rules: Safety training for all handlers; emergency procedures established for accidental exposure or release
