Molecular Weight: 198.23 g/mol
Inhalation: Move person to fresh air quickly, keep at rest in comfortable position, seek medical attention
Skin Contact: Remove contaminated clothing, immediate and thorough washing with plenty of water and soap, seek prompt medical advice
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present and easy, continue rinsing, urgent medical attention required
Ingestion: Rinse mouth, never administer anything by mouth if victim is unconscious, seek immediate medical assistance, do not induce vomiting unless specifically directed by medical personnel
Most Important Symptoms: Signs of poisoning include nausea, vomiting, dizziness, skin or eye irritation, evidence of liver or blood effects with repeated exposure
Immediate Medical Attention Required: Yes, after any significant exposure
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide extinguishers, avoid direct water streams
Unsuitable Extinguishing Media: Water jets may spread contamination or create hazardous runoff
Specific Hazards: Decomposition yields toxic gases including nitrogen oxides, carbon monoxide, and possibly aniline vapors
Protective Equipment: Firefighters should use full protective gear including self-contained breathing apparatus
Special Procedures: Evacuate area, contain runoff, notify authorities if large quantities involved
Personal Precautions: Evacuate nonessential personnel, ventilate area, use appropriate protective equipment (respirator, gloves, chemical goggles)
Environmental Precautions: Prevent entry into sewers, watercourses, or soil, inform environmental authorities in case of large spill
Clean-Up Methods: Contain with inert absorbent material (sand, vermiculite), scoop up and place in labeled, sealable containers, wash down surface with mild detergent and water, collect wastewater for disposal
Decontamination: Dispose of all cleaning materials as hazardous waste under local and national regulations
Safe Handling: Work only in well-ventilated areas, avoid dust formation, wear suitable face/skin protection, avoid ingestion, inhalation, and skin contact
Safe Storage: Store in tightly closed containers, protect from light, heat, and moisture, label containers clearly, keep away from incompatible substances such as strong oxidizers, acids, and bases
Storage Area Requirements: Use dedicated, secure, dry storage, with spill containment measures, suitable signage, access restricted to trained personnel
Hygiene Recommendations: Wash thoroughly after handling, keep street clothing separate, provide shower and eyewash facilities
Occupational Exposure Limits: No specific OSHA or ACGIH limits established, limit exposure as much as possible
Engineering Controls: Use fume hoods or chemical glove boxes, provide local exhaust ventilation, monitor air quality regularly
Personal Protective Equipment: Wear impervious gloves (nitrile or butyl rubber), long-sleeved chemical-resistant clothing, full-face respirator with organic vapor cartridge for potential airborne exposure, chemical safety goggles
Hygiene Measures: No food, drinks or smoking in work areas, regular handwashing, contaminated clothing should be removed and laundered before reuse
Appearance: Pale yellow to orange crystals or powder, slight aromatic odor
Melting Point: 171 – 177°C
Boiling Point: Decomposes above 250°C
Solubility: In water - low; more soluble in organic solvents such as ether, benzene, and ethanol
Density: 1.25 g/cm³ (approximate)
Vapor Pressure: Very low at ambient conditions
Flash Point: Not readily flammable, but can burn when heated
pH: Not applicable (neutral compound)
Partition Coefficient (log Pow): 3.5 – 4.2 (estimated)
Chemical Stability: Stable under normal storage conditions away from incompatible substances and excessive heat
Hazardous Reactions: Avoid contact with strong oxidizers, acids, bases, and reducing agents
Conditions to Avoid: Prolonged exposure to heat, UV light, sources of ignition, strong acids or bases
Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, may form toxic aromatic amine vapors upon decomposition
Acute Toxicity: Harmful if swallowed, inhaled, or absorbed through skin; LD50 (rat, oral): ~1120 mg/kg, LD50 (rabbit, dermal): data not fully established
Chronic Effects: Long-term exposure may cause liver, blood, and kidney damage; carcinogenic potential seen in animal studies
Routes of Exposure: Inhalation, ingestion, dermal, eye
Symptoms: Nausea, headaches, irritation, weakness, possible delayed organ damage with repeat exposure
Carcinogenicity: Classified as possibly carcinogenic to humans (IARC Group 2B); not listed by NTP, not specifically regulated by OSHA
Mutagenicity/Teratogenicity: Possible mutagen concerns based on structural similarity to other nitrosamines
Aquatic Toxicity: Toxic to aquatic life, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Expected to be persistent due to low biodegradability
Bioaccumulative Potential: High; log Kow indicates potential for accumulation in aquatic organisms
Mobility in Soil: Low solubility, tends to adsorb to soils
Other Adverse Effects: Breakdown products may also be hazardous to wildlife; proper containment and disposal critical to prevent environmental release
Waste Treatment Methods: Collect and dispose of contents and container in accordance with local, regional, national, and international regulations
