Chemical Name: 2,4-Diaminotoluene Sulfate
Synonyms: Toluene-2,4-diamine sulfate
Chemical Formula: C7H10N2 · H2SO4
Physical Form: Powder or granular solid, usually with a beige to tan appearance
Uses: Intermediary in dye manufacturing, occasional use in some chemical syntheses
Odor: Faintly aminic
Classification: Toxic if inhaled or absorbed through skin; harmful if swallowed; possible carcinogen based on animal studies
Acute Effects: Skin and eye irritation, respiratory tract discomfort or injury, nausea
Long-Term Risks: Potential impact on liver, kidneys, blood system; may promote tumors with repeated exposure
Environmental Impact: Hazardous to aquatic organisms, dangerous if it enters water systems
Risk of Combustion: Although not highly flammable on its own, can emit toxic gases during a fire
Main Component: 2,4-Diaminotoluene (typically over 80% by weight)
Associated Acid: Sulfate ion from sulfuric acid treatment
Contaminants: Possible trace anilines and related aromatic amines
CAS Number: 615-50-9
Inhalation: Remove to fresh air, monitor for breathing difficulty, seek medical attention if symptoms worsen
Skin Contact: Immediate, thorough washing with soap and water; removal of contaminated clothing
Eye Contact: Rinse with clean water for at least 15 minutes; avoid rubbing; obtain medical care
Ingestion: Do not induce vomiting; rinse mouth, get medical help quickly
Notes to Physician: Treatment focuses on controlling symptoms and supporting organ function, especially with suspected methemoglobinemia or organ toxicity
Extinguishing Media: Dry chemical, foam, or carbon dioxide best controls powder fires
Hazards During Fire: Poisonous vapors such as nitrogen oxides, sulfur oxides, and toluene derivatives may form
Protective Gear: Use self-contained breathing apparatus, chemical-resistant clothing
Special Tactics: Stay upwind, keep runoff water out of sewers or natural waterways
Containment: Isolate spill area; prevent substance from reaching drains or soil
Cleanup Strategy: Avoid direct contact; sweep or shovel into closed, labeled containers; minimize dust
Personal Protection: Gloves, face shield or safety glasses, long-sleeved clothing
Decontamination: Wash area with plenty of water after removing the material
Safe Handling: Avoid inhaling dust or vapors, prevent contact with skin and eyes, work in ventilated spaces
Storage Recommendations: Keep containers tightly closed, away from incompatible substances like oxidizers or acids, store in a cool, dry, well-ventilated area
Incompatible Materials: Strong oxidizing agents, strong acids, chlorine-releasing chemicals
Good Practice: Use personal protective equipment and avoid eating, drinking, or smoking in handling areas
Engineering Controls: Local exhaust ventilation, process enclosures, safety showers, eye wash stations in work area
Personal Protective Equipment: Chemical-resistant gloves, protective goggles, suitable protective clothing, respiratory protection in areas of dust or poor ventilation
Hygiene Measures: Wash hands and exposed skin thoroughly after handling; remove contaminated clothing
Workplace Exposure Limits: Check national occupational safety guidelines for exposure limits, as some countries regulate levels due to toxicity and possible carcinogenic risk
Appearance: Off-white to tan granules or powder
Melting Point: Around 104°C (sulfate form; free base melts near 99°C)
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Water-soluble due to sulfate; variable in organic solvents
Odor Threshold: Detectable at very low airborne concentrations
Vapor Pressure: Negligible at room temperature
Chemical Stability: Stable under normal conditions, but sensitive to heat and light which may decompose the material
Conditions to Avoid: High temperatures, strong acids or alkalis, oxidizing agents
Hazardous Decomposition: Risk of producing toxic vapors including nitrogen oxides and sulfur oxides
Polymerization Risk: Not expected under normal storage or use
Likely Routes of Exposure: Skin and eye contact, inhalation of dust, accidental ingestion
Symptoms: Headache, drowsiness, skin rash, respiratory tract discomfort, nausea, blue lips or fingernails from methemoglobinemia
Chronic Exposure: Potential for cancer development based on animal data, risk of liver, kidney, or blood disorders after repeated contact
Carcinogenicity: Some national health agencies list 2,4-diaminotoluene as a possible or suspected carcinogen
Reproductive Effects: No clear evidence in humans, but structural similarity to other aromatic amines causes concern
Sensitization: May trigger allergic skin reactions or asthma-like symptoms in sensitive individuals
Aquatic Toxicity: Very dangerous to fish and aquatic invertebrates even at low concentrations
Persistence: Degrades slowly in water systems; breakdown products may be toxic
Mobility: Dissolves in water, can leach through soil and reach groundwater
Bioaccumulation: Low to moderate tendency, but environmental persistence increases risk to ecosystems
Waste Handling: Collect in clearly labeled, sealed containers; never rinse into drains, sewers, or open environment
Disposal Method: Send to authorized hazardous waste processing facility
Incineration: Possible under controlled conditions, but monitor exhaust gases for harmful emissions
Other Information: Container residues are hazardous; treat packaging as chemical waste
Hazard Classification: Toxic solid, organic; may fall under Class 6 for toxic substances depending on country
Packaging: Secure, leak-proof containers designed for hazardous solids
Labeling: Clearly marked with hazard warnings; document chemical name and toxic risk for shippers and emergency responders
Transport Risks: Avoid jarring, moisture, and extreme heat; immediate cleanup for spills is essential to protect handlers and the public
Workplace Limits: Many countries control the maximum allowable workplace concentrations; check local regulations for compliance
Classification: Designated as hazardous due to acute and chronic toxicity as well as possible carcinogenic effects
Environmental Controls: National and regional agencies regulate discharge to water and air; companies handle substantial paperwork before approving handling or disposal
Right-to-Know Laws: Many jurisdictions require full safety disclosure to workers and downstream users; training on safe use and emergency procedures is non-negotiable in responsible workplaces
