Impurities/Additives: May contain traces of unreacted phthalonitrile and phthalocyanine precursors, typically less than 1% by mass
Concentration: ≥ 98% Tetraaminophthalonitrile
Occupational Exposure Limits: None established specifically; treat as a generic irritant
Inhalation: Move person to fresh air immediately, help maintain comfortable breathing; if symptoms persist, seek medical care
Skin Contact: Wash area with soap and water, remove affected clothing, persistent irritation needs medical evaluation
Eye Contact: Flush eyes gently with water for at least 15 minutes, hold eyelids open, remove contact lenses if present and easy to do, get medical help if discomfort lingers
Ingestion: Rinse mouth, never induce vomiting unless directed by healthcare provider, call poison control for instructions
Notes to Physician: Treat symptomatically, examine for allergic reaction or respiratory distress
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, avoid water jets directly on the chemical
Specific Hazards: Decomposes under fire conditions to release toxic fumes like nitrogen oxides, hydrogen cyanide, carbon monoxide
Firefighter Protection: Full protective gear including self-contained breathing apparatus, approach from upwind, avoid inhalation of smoke and dust
Explosion Hazard: Not classified as explosive, but dust may combust in air under certain conditions
Firefighting Procedures: Cool containers exposed to flames using water spray, prevent runoff into drains or waterways
Personal Precautions: Use appropriate respiratory and skin protection, keep unprotected people away, minimize dust
Environmental Precautions: Prevent chemical from entering drains, streams, or soil, use containment dikes if necessary
Methods for Cleanup: Sweep or vacuum up using equipment with HEPA filter, collect in labeled containers for disposal, avoid generating dust
Spill Area Ventilation: Open windows, use local exhaust if possible, clean thoroughly after removal
Small Spills: Use damp cloths or disposable wipes to pick up, dispose of with solid waste
Safe Handling Practices: Work in well-ventilated areas, avoid eating or drinking where substance is used, wash up before breaks and after shift
Technical Measures: Apply general and local exhaust; use non-sparking tools if dust clouds can form
Storage Conditions: Store in tightly closed original containers, keep away from incompatible materials like oxidizers and acids, protect from moisture and direct sunlight
Packaging Materials: Use strong, sealed containers impervious to dust and chemicals
Incompatibilities: Strong acids, strong oxidizers, reducing agents
Engineering Controls: Local exhaust ventilation, dust extraction systems, closed handling if available
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), safety goggles, protective lab clothing, suitable dust mask or respirator if ventilation isn’t enough
Hygiene: Wash up after handling, keep contaminated clothing out of eating areas, change gloves if contaminated
Environmental Controls: Collect powder at source, filter exhaust before release outdoors
Workplace Monitoring: Regularly check air for dust levels, provide eyewash stations nearby
Appearance: Fine crystalline powder, color usually off-white to tan
Odor: Faint aromatic or amine-like smell
Melting Point: 285–295°C (decomposes)
Solubility: Very low in water, more soluble in dimethyl sulfoxide and other polar aprotic solvents
Density: 1.45–1.50 g/cm³
Boiling Point: Not applicable (decomposes before boiling)
pH: Not measured due to low solubility in water
Volatility: Negligible at room temperature
Flash Point: Not flammable under standard conditions
Other Properties: Stable under normal temperature and pressure, avoid exposure to hot surfaces
Chemical Stability: Stable under recommended storage, decomposes at elevated temperature
Reactivity: May react with strong acids or oxidizing agents; generates hazardous gases on decomposition (nitrogen oxides, cyanide compounds)
Hazardous Reactions: Dangerous fumes released if mixed with reducing agents, acids, or subjected to strong heat
Conditions to Avoid: Moisture, extreme heat, incompatible chemicals
Hazardous Decomposition Products: Nitrogen oxides, hydrogen cyanide, carbon monoxide, ammonia gases
Likely Routes of Exposure: Inhalation, skin absorption, eye contact, accidental ingestion
Health Effects: Irritation to mucous membranes, dermatitis, headache, nausea, in severe cases possible respiratory sensitization
Acute Toxicity: Rat oral LD50 estimated at 1000-2000 mg/kg (moderately toxic)
Chronic Effects: Limited data, repeated exposure may sensitize or cause allergies; not listed as carcinogen
Mutagenicity: Not enough data for full evaluation
Symptoms of Exposure: Sneezing, eye watering, persistent cough, itching
Ecotoxicity: Moderate to high toxicity to aquatic organisms, danger of accumulation in aquatic food chains
Persistence and Degradability: Biodegradation expected to be slow, strong binding to soil particles
Bioaccumulation Potential: No strong tendency for bioaccumulation reported, but long-term risks possible
Mobility in Soil: Low mobility, material tends to settle in sediments
Other Adverse Effects: Avoid contamination of surface waters, general degradation not rapid
Waste Handling: Dispose as hazardous chemical waste according to local regulations
Methods of Disposal: Use properly permitted incineration or chemical landfill, do not dump into drains or natural ecosystems
Contaminated Packaging: Rinse containers (if permitted), dispose with hazardous waste
Special Precautions: Avoid landfill if possible, track inventory to minimize waste generation
UN Number: Not assigned for bulk transportation, handle as chemical under local requirements
Transport Hazard Class: Not rated; treat as hazardous substance for safe handling
Packaging Group: III (if applicable for substance type)
Proper Shipping Name: Tetraaminophthalonitrile
Special Transport Precautions: Avoid exposure to moisture or temperature extremes, secure containers in upright position, keep away from reactive chemicals, clearly label
Marine Pollutant: Not specifically listed, but high aquatic toxicity suggests extra care during marine transport
OSHA Status: Not specifically regulated, OSHA General Duty Clause applies due to irritant effects
TSCA Status: Listed or exempted
SARA Title III: Not subject to reporting, but handle waste streams as hazardous
REACH Registration: Not registered, check status for import/use in Europe
Other Regulations: State/local worker protection and environmental release rules apply, label according to national hazard communication standards, safety data must be provided to users in workplace
