Name: 2,4-Diaminotoluene
Chemical Formula: C7H10N2
Synonyms: Toluene-2,4-diamine, 2,4-TDA
Appearance: Pale yellow to brownish crystalline solid
Odor: Mild, aromatic, somewhat unpleasant
Uses: Precursor for dyes and pigments, intermediate for chemical synthesis
Major Risks: Toxic on skin contact and if inhaled, severe eye damage, suspected carcinogen, may cause genetic defects, harmful to aquatic life
Routes of Exposure: Inhalation, skin absorption, ingestion
Target Organs: Liver, kidneys, blood, respiratory tract
Warning Symbols: Skull and crossbones (acute toxicity), exclamation mark (irritant)
Harmful Effects: May be fatal if inhaled, causes skin and eye burns, possible long-term effects such as cancer
Main Component: 2,4-Diaminotoluene, minimum purity 98%
Common Impurities: Isomeric diaminotoluenes, water, trace organic solvents
General: Move affected person to fresh air, remove contaminated clothing
Inhalation: Seek urgent medical help, monitor for breathing difficulty
Skin Contact: Wash thoroughly with soap and water, seek medical attention for irritation or burns
Eye Contact: Flush eyes with water for at least 20 minutes, get prompt medical attention
Ingestion: Do not induce vomiting, rinse mouth, get immediate medical help
Sensitivity: Substance is combustible, forms toxic fumes under fire conditions such as nitrogen oxides and carbon monoxide
Recommended Extinguishing Media: Dry chemical, foam, or carbon dioxide
Special Hazards: Sealed containers may rupture from heat, decomposition gives hazardous gases
Protection for Firefighters: Wear self-contained breathing apparatus and full protective gear
Personal Precautions: Avoid breathing dust or vapors, prevent skin and eye contact, ventilate area
Containment: Stop leak if safe to do so, avoid formation of dust
Cleanup: Collect material using inert absorbent, place in suitable container for disposal, wash spill area thoroughly
Environmental Caution: Prevent material from entering drains or watercourses
Handling: Maintain good ventilation, avoid exposure, use appropriate PPE, handle away from sources of ignition
Storage: Keep container tightly closed, store in cool, dry, well-ventilated place, separate from oxidizers and acids
Incompatibilities: Strong acids, strong oxidizing agents
Recommended Engineering Controls: Fume hood or local exhaust, enclosed handling if possible
Personal Protection: Chemical-resistant gloves, safety goggles, long sleeves, face protection, respiratory protection when dust or vapor possible
Hygiene: Wash hands after use, remove contaminated clothing promptly, no eating or drinking in area
Permissible Exposure Limits: Consult national regulations, as limits vary (generally low permissible levels)
State: Solid at room temperature
Color: Pale yellow to brownish
Melting Point: Around 99°C (210°F)
Boiling Point: Roughly 302°C (576°F) at standard pressure
Solubility: Slightly soluble in water, more soluble in organic solvents
Vapor Pressure: Low at ambient conditions
Odor: Characteristic, mildly aromatic
Density: Approximately 1.12 g/cm³
Chemical Stability: Stable under normal conditions, decomposes on exposure to heat
Reactivity: Reacts with strong oxidants and acids, forms hazardous decomposition products
Hazardous Decomposition: Carbon monoxide, carbon dioxide, nitrogen oxides, toxic fumes
Other Issues: Avoid high heat, sparks, open flames
Acute Exposure: Highly toxic on inhalation and skin contact, severe irritation and burns
Chronic Exposure: Suspected carcinogen, possible mutagenic effects, damage to liver and kidneys possible through repeated exposure
Symptoms: Cough, sore throat, skin redness, eye burns, nausea, headache, anemia with prolonged exposure
Carcinogenicity: Classified as possibly carcinogenic to humans by some agencies
Environmental Impact: Harmful to aquatic life with long lasting effects
Mobility: Moderately persistent in soil and water due to slow degradation
Bioaccumulation: Low potential, but breakdown products can affect organisms
Toxicity to Aquatic Systems: Immediate and chronic toxicity to fish and invertebrates observed in some tests
Preferred Methods: Incineration at suitable facility with scrubber for toxic gases
Restrictions: Do not release to environment, do not landfill without professional assessment due to toxicity
Special Instructions: Treat as hazardous waste, follow local and national regulations, avoid direct contact
Container Disposal: Triple rinse and render unusable before disposal through hazardous waste route
Classification: Listed as hazardous for transport, toxic solid, organic, n.o.s.
Packaging: Use tightly sealed, corrosion-resistant containers
Labels: Toxic, environmental hazard symbols required
Precautions: Handle only by qualified personnel, keep separated from foodstuffs and animal feed
Major Legal Status: Controlled under national and international chemical safety regulations due to toxicity
Worker Protection: Subject to workplace health and safety laws, PPE and training required for regular use
Emission Controls: Crosses hazardous thresholds for air and water releases in many regions
Special Reporting: May require reporting to environmental or occupational health authorities if released or handled above definite amounts
