Common Name: 2,6-Diaminotoluene
Chemical Formula: C7H10N2
Synonyms: Toluene-2,6-diamine, 2,6-Toluenediamine
Appearance: Pale gray to violet crystalline solid
Odor: Ammonia-like
Use Cases: Building block in manufacturing dyes, pigments, polymers, hair coloring chemicals
Possible Acute Effects: Headache, nausea, dizziness, irritation to eyes and respiratory tract, possible skin sensitization
Chronic Risks: Repeated exposure poses threats such as methemoglobinemia, which reduces blood’s oxygen-carrying ability, and liver or kidney damage in long-term industrial settings
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion (rare outside of accidents)
Hazard Classification: Harmful by inhalation and skin absorption; suspected mutagenic hazard
Risk Phrases: Harmful if swallowed or inhaled; risk of serious damage to eyes; potential for causing skin allergy
Chemical Name: 2,6-Diaminotoluene
Purity: High-purity preparations typically exceed 98%
Impurities: Other isomeric toluenediamines in trace amounts
Inhalation: Move affected person to fresh air right away, provide oxygen if breathing becomes labored, seek medical help
Skin Contact: Rinse skin thoroughly using copious amounts of water, remove contaminated clothing or gear promptly, avoid scrubbing skin
Eye Contact: Flush open eyes with gentle, running water for at least 15 minutes, hold eyelids apart, immediate medical attention is strongly advised
Ingestion: Rinse mouth with water, do not induce vomiting, medical attention required due to risk of systemic toxicity
Flammability: Solid form poses low fire risk, but combustible dust may ignite under certain conditions
Hazardous Combustion Products: Toxic gases, such as nitrogen oxides and carbon monoxide, may form in a fire
Suitable Extinguishing Media: Dry chemical, foam, CO₂, or water spray to knock down flames
Protective Action for Firefighters: Full protective gear with self-contained breathing apparatus recommended in confined fires, avoid inhaling combustion gases
Personal Precautions: Don’t handle spills without gloves and eye protection, ventilate area
Spill Cleanup: Scoop up solid without raising dust, place in sealed non-reactive container
Environmental Protection: Prevent entry into drains, waterways, or soil due to risk of ecological damage
Decontamination Advice: Wash affected surfaces with water and mild detergent after bulk material removal
Handling: Practice good hygiene, use in well-ventilated work areas, avoid contact with eyes, skin, and clothing, use extraction hoods if available
Storage: Store tightly closed in cool, dry, ventilated place, protect from incompatible materials such as strong oxidizers and acids, label clearly to prevent mixing or accidental contact
Engineering Controls: Local exhaust ventilation and process enclosures lower airborne exposure
Exposure Limits: Some jurisdictions set limits, consult local regulations
PPE Recommendations: Nitrile or neoprene gloves, chemical goggles, lab coats, and, for high-dust operations, particulate respirators
Hygiene Tips: Remove contaminated clothing after work, always wash hands before eating or drinking
Physical State: Solid, crystal or powder
Color: Pale gray to violet
Odor: Sharp, ammonia-like
Melting Point: Around 104°C
Boiling Point: Around 300°C
Solubility: Soluble in water, more so in organic solvents
Vapor Pressure: Low at room temperature
Stability under Common Lab Conditions: Stable when kept dry and at room temp, but will oxidize in moist air
Chemical Stability: Stable under recommended storage conditions, but interaction with air and moisture promotes oxidation
Incompatible Materials: Avoid strong oxidizers, acids, and acyl chlorides
Decomposition Risks: Prolonged or severe heat releases irritating, toxic fumes
Polymerization Hazard: No reported risk
Acute Toxicity: Oral ingestion in moderate amount can produce nausea, vomiting, methemoglobinemia, and even convulsions
Skin Absorption: Small amounts enter bloodstream, raising health concern during regular exposure
Carcinogenicity: No confirmed cancer link for this isomer, but related chemicals draw IARC scrutiny
Other Health Effects: Allergic dermatitis, respiratory irritation, possible eye damage with direct contact
Susceptible Groups: Workers with respiratory illnesses or skin sensitivity at higher risk
Environmental Fate: Breaks down gradually via microbial action, but may persist in soil and water for weeks under some conditions
Aquatic Toxicity: Harmful to aquatic life even at low concentrations, particularly for fish and other gill-bearing organisms
Bioaccumulation: Avoids significant food chain accumulation, but ongoing monitoring remains wise where effluent risk exists
Recommendations: Prevent releases to water, ensure good wastewater treatment, monitor discharge sites if used at scale
Waste Management: Dispose as hazardous chemical waste under local, national guidelines
Incineration: Thermal destruction in controlled facilities keeps byproducts contained
Landfill Suitability: Strongly discouraged, as leaching into water table threatens public health
Resource Recovery: Not cost-effective; contamination outweighs benefit
DOT/ADR Classification: US and European transport regulations generally list this compound as hazardous, so label shipments clearly
Packaging Protocol: Use sealed, chemically compatible drums or containers, cushion against impact and moisture
Emergency Response Number: Carrier protocols dictate response in spills or leaks
Special Transport Notes: Avoid high temperature and direct sunlight during longer hauls
Right-To-Know Status: Many local environmental and labor-health laws require that all employees receive hazard information
Environmental Listing: Entered in lists governing hazardous waste, industrial discharge, chemical storage
Workplace Compliance: OSHA and similar authorities stress the need for ongoing staff training, chemical inventory management, documented use of engineering controls and PPE
Labeling/Waste: Classification as hazardous waste in North America and parts of Europe invokes site inspection requirements for medium to large users
