Chemical name: Trinitroanisole. Common synonyms: 2,4,6-Trinitroanisole. Chemical formula: C7H5N3O7. Molecular weight: 243.13 g/mol. Appearance: Pale yellow crystalline powder can draw the eye, but not for the right reasons. Odor: Faint, sometimes sweet, sometimes just harsh chemical. Uses: Forms part of explosive formulations and specialty chemical synthesis. CAS Number: 532-99-8.
Hazard class: Explosive, toxic, and possibly an irritant. Health risks: Exposure means trouble for skin, eyes, lungs, or with accidental swallowing. Main danger: Exposure to heat or impact can trigger a violent reaction. Routes of entry: Inhalation, skin and eye contact, ingestion. Physical hazards: Shock sensitivity makes this substance a ticking concern. Environmental hazards: Persistent in soil and water, potentially damaging aquatic systems. Risk phrases: Danger of explosion by shock, friction, fire, or other sources of ignition.
Main constituent: 2,4,6-Trinitroanisole. Percentage: Typically over 95% pure, but never count out minor impurities from synthesis. Impurities: Might include trace polynitro by-products, not usually separated except for research-grade batches. Hazardous impurities: Some may add to overall risk, but the pure product carries enough risk on its own.
Eye contact: Rinse carefully with water, keep eyelids open, no rubbing. Skin contact: Remove any contaminated clothing, wash skin with soap and plenty of running water. Inhalation: Move to fresh air, find medical attention if effects linger. Ingestion: Never try to induce vomiting, rinse mouth, seek medical help. Signs and symptoms: Headache, cough, nausea, eye or skin irritation, possibly worse with prolonged or high-level exposure.
Suitable extinguishing media: Dry chemical, foam, or water spray in light mist only. Unsuitable media: Direct strong water jets can spread contamination. Hazards: Burns with dense, toxic smoke containing oxides of nitrogen. Protective gear: Full turnout gear, self-contained breathing apparatus, avoid water runoff. Special notes: Evacuate area, approach from upwind, avoid handling dry or spilled product during a fire—heat can set it off.
Personal precautions: Evacuate if needed, keep sources of ignition far away, wear full protective gear. Environmental precautions: Keep out of drains, ditches, and natural waterways—think long-term impact. Cleaning up: Sweep up gently without sparking, use non-sparking tools, store in a safe, labeled container for proper disposal. Ventilation: Increase fresh air if safe to do so.
Handling: Use with caution, never alone or distracted. Precautions: No open flames, no smoking, work in grounded, spark-proof environments. Storage conditions: Cool, dry, tightly sealed containers, far from incompatible substances (acids, bases, reducing agents). Storage location: Well-ventilated area, explosive-grade magazine, limited access by trained staff only. Special concerns: Keep away from heat, shock, and vibration; treat as you would high-powered fireworks, but take it more seriously.
Engineering controls: Fume hoods, explosion-proof ventilation, and remote handling setups. Personal protective equipment (PPE): Chemical splash goggles, gloves (nitrile or neoprene), flame-resistant lab coat, sometimes face shields. Hygiene: Wash hands before eating, no food or drink in work area, remove contaminated clothing. Respiratory protection: NIOSH-approved respirator if dust or fumes exceed safe levels.
Appearance: Pale yellow solid, crystalline. Odor: Slight, often unremarkable but not to be ignored. Melting point: 81–83°C. Boiling point: Decomposes before boiling. Solubility: Sparse in water, more in organic solvents like acetone or ethanol. Density: About 1.65 g/cm³. Vapor pressure: Low at room temperatures. Other properties: Highly energetic with a reputation for sudden and complete combustion given the opportunity.
Chemical stability: Stable under recommended storage, but don’t count on leniency—sensitive to heat, friction, and impact. Incompatibilities: Strong acids, bases, reducing agents. Hazardous decomposition products: Nitrogen oxides, carbon monoxide, carbon dioxide, methyl ethers possible on breakdown. Reactivity: High, even slight ignition sources need avoidance. Polymerization: Doesn’t apply, but unsafe reactions are always possible in failing containment.
Acute toxicity: Inhalation leads to headache, nausea, dizziness, even blood disorders with regular exposure. Skin/eye contact: Can cause redness, dry or cracked skin, severe irritation. Chronic exposure: Liver, kidney, and blood effects not ruled out. Carcinogenicity: Not well studied, so treat it with caution. Other risks: Potential for cyanosis, methemoglobinemia with significant exposure.
Persistence: Sticks around in soil and water, doesn’t readily break down. Bioaccumulation: Unlikely in complex organisms, but aquatic and plant life can still absorb risky amounts. Aquatic toxicity: Dangerous to fish and invertebrates, possibly creating dead zones in streams or ponds. Mobility: Moves through soil if spilled, can leach into groundwater.
Waste method: Treat as hazardous, incinerate in specialized explosive waste incinerators if possible. Container management: Decontaminate before reuse or dispose according to local chemical hazards protocol. Environmental care: Never pour down drains, toilets, or around green spaces, since once it’s out, retrieval or remediation grows expensive and slow.
UN Number: UN 1321. Shipping name: Explosive, n.o.s. (not otherwise specified). Transport class: Division 1.1D explosive. Documentation: Strictly regulated; trained operators only. Special notes: Ground, air, sea transport demands government notification and strict manifest documentation. Packages require blast-resistant containers, shock-absorbing packaging, and never travel with flammables or other explosives in the same load.
International status: Listed in various international conventions for restricted substances. National regulations: Falls under explosives and dangerous goods rules—mere possession without permits counts as a crime in many places. Worker safety: OSHA and equivalent agencies designate strict workspace exposure and training. Environmental controls: National and regional authorities often require prompt reporting of accidental releases, waste treatment, or storage incidents, with heavy fines for slip-ups.
