Recommended Uses: Used in synthesis of dyes, pigments, and as an intermediate in organic chemistry research
CAS Number: 97-02-9
Hazard Classification: Classified as hazardous; may pose risk through inhalation, ingestion, or skin contact
Acute Health Risks: Can cause irritation to eyes, skin, and respiratory tract; probable harmful effects on blood
Chronic Health Risks: Prolonged or repeated exposure may impact liver and kidneys
Fire and Explosion: Finely divided particles can form explosive mixtures in air; dust poses risks in storage and transfer
Signal Words: Warning for contact and inhalation risk
Labels Required: Toxic, irritant, environmental hazard
Name: 2,6-Dinitroaniline
Concentration: Usually 98-100% pure in laboratory and industry settings
Impurities: Minor presence of isomers or unreacted starting materials
Inhalation: Move person to fresh air without delay; seek medical help if breathing difficulty persists
Skin Contact: Remove contaminated clothing, wash affected area with soap and water; persistent irritation should be managed by a healthcare professional
Eye Contact: Flush with plenty of water for at least 15 minutes; keep eyelids apart; medical attention is necessary for pain or vision changes
Ingestion: Rinse mouth with water; do not induce vomiting; prompt medical help is critical to manage possible systemic effects
Suitable Extinguishing Media: Dry chemical, carbon dioxide, or foam
Unsuitable Media: Direct stream of water can spread the material or create hazardous runoff
Special Hazards: May emit toxic fumes including nitrogen oxides when burning
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear to avoid skin and respiratory exposure
Personal Precautions: Use appropriate personal protection such as gloves and dust mask
Spill Cleanup: Avoid dust generation; sweep or scoop up solid material, place in suitable container for disposal
Environmental Precautions: Prevent spill from entering water sources or soil to limit long-term environmental damage
Decontamination: After removal, wash area with soap and water, ventilate affected space well
Handling: Work in well-ventilated spaces; minimize dust generation; avoid direct skin or eye contact
Storage: Store in cool, dry, well-ventilated area, away from oxidizers and sources of ignition; containers remain tightly closed
Incompatibilities: Strong oxidizing agents, reducing agents, combustible materials
Engineering Controls: Use local exhaust systems to reduce airborne dust, apply general room ventilation
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, appropriate dust mask or respirator
Skin Protection: Wear lab coat or suitable work clothes that cover exposed skin
Hygiene Measures: Wash hands thoroughly after use; do not eat, drink, or smoke in handling areas
Exposure Limits: No formal occupational exposure limits established worldwide, but keep workplace concentrations as low as possible
Physical State: Crystalline solid
Color: Yellow or orange
Odor: Virtually odorless
Melting Point: Around 150-152°C
Solubility: Slightly soluble in water, more soluble in organic solvents such as ethanol and acetone
Vapor Pressure: Negligible at room temperature
Density: Typically about 1.54 g/cm3
Flash Point: Not easily flammable; precise value often unspecified due to low volatility
Chemical Stability: Stable under normal temperatures and pressures
Reactivity: May react with strong oxidizers and reducing agents
Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, other hazardous gases possible during heating or fire
Polymerization: Not known to undergo hazardous polymerization in normal conditions
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Effects: Irritation to mucous membranes and skin, possible effects on hemoglobin and blood system
Chronic Exposure: Prolonged or repeated doses can cause damage to liver, kidneys, and blood-forming organs
Symptoms of Overexposure: Headache, dizziness, cyanosis (bluish skin), nausea
Carcinogenicity: Not listed by IARC, NTP, or OSHA for human carcinogenicity
Mutagenicity and Teratogenicity: Data limited; laboratory studies with similar compounds suggest possible genetic effects, but evidence remains sparse
Aquatic Toxicity: Toxic to aquatic life; significant releases can damage fish, algae, and invertebrates
Persistence and Degradability: Compound degrades slowly in environment; may persist in soil and sediment
Bioaccumulation Potential: Moderate potential for bioaccumulation, particularly in aquatic species
Mobility in Soil: Low to moderate, with some risk of groundwater contamination if spilled in large quantities
Other Environmental Hazards: Broad threats to aquatic habitats underline the importance of careful handling and disposal
Disposal Methods: Collect as hazardous chemical waste; incinerate according to local regulations using licensed facilities
Do Not Dump: Strong recommendation to avoid discharge to sewer systems, surface water, or soil
Container Management: Use proper chemical waste containers; decontaminate if possible or treat as hazardous waste
UN Number: UN not universally assigned for this specific substance
Shipping Name: Dinitroaniline compound
Hazards During Transport: May cause dust explosion if finely divided and exposed to sparks or flame during shipping
Packing Group: Typically handled as hazardous; check carrier and country-specific transport rules
Special Precautions: Secure packaging to avoid spills and physical damage during transit
Regulatory Status: Controlled under chemical regulations in many countries based on toxicity and environmental impact
Labeling Requirements: Hazard pictograms for toxicity and environmental damage
Workplace Controls: Facilities using the compound must comply with workplace safety and chemical handling regulations
Reporting Requirements: Spills and accidental releases can trigger mandatory reporting to local authorities under environmental protection laws; compliance is enforced to minimize community and environmental harm
