Chemical Name: Trimethyldialuminum Tribromide
Common Uses: This organoaluminum compound enters research spaces and chemical manufacturing because its reactivity can boost organic reactions that need strong Lewis acids.
Appearance: Clear to light yellow liquid, not something you’d mistake for water. A whiff gives it away—it produces strong, pungent fumes.
Chemical Formula: Al2Br3(CH3)3
CAS Number: 14632-36-5
Synonyms: None appear in major chemical databases, so shops and labs stick to its real name.
Physical Hazards: Highly reactive with moisture in the air—contact with water or damp air can trigger a violent reaction that releases toxic and corrosive gases.
Health Risks: Exposure can inflict severe burns on skin and eyes. Inhalation causes respiratory distress, coughing, and potential lung damage. Ingestion leads to corrosive burns in the mouth, throat, and stomach.
Environment Hazards: Escaped liquid or fumes threaten aquatic life and the environment because of its long-lasting effects and toxicity.
Main Component: Trimethyldialuminum Tribromide — nothing else hides in the bottle, which makes reactivity easy to predict but demands focus with every step.
Concentration: Pure substance without significant impurities.
Inhalation: Guide affected person to fresh air as soon as possible. Oxygen and medical support might be needed if breathing difficulties set in. Remaining near the source invites further harm.
Skin Contact: Remove contaminated clothing. Wash area thoroughly with lots of water, without delay. Chemical burns demand immediate medical attention.
Eye Contact: Rinse carefully with plenty of water for several minutes. Keep eyelids lifted to flush thoroughly. Do not risk delay—seek emergency medical help straight away.
Ingestion: Never induce vomiting. Rinse out mouth with water and call for urgent medical care. Long-term damage starts fast in the digestive tract.
Suitable Extinguisher: Use dry powder or sand. Water or foam brings more danger—the chemical reacts violently with them, and the resulting fumes threaten anyone close.
Specific Hazards: Fire releases hydrogen bromide, aluminum oxide, and methyl bromide gases—all toxic, corrosive, and hazardous if inhaled.
Protective Equipment: Full-face self-contained breathing apparatus and chemically resistant suit are not optional for firefighting here.
Other Tips: Remove unaffected containers from fire zone if safe. Risk of explosions spikes if fire spreads to unsealed containers.
Personal Precautions: Only trained staff in full protective gear should handle cleanup. This includes gloves, face shield, suit, and respiratory protection.
Environmental Precautions: Prevent spillage from entering water systems or drains. Soil, groundwater, and surface water do not forgive carelessness.
Spill Cleanup: Cover with dry inert material like sand, lime, or graphite. Scoop up with spark-safe tools for disposal. Never wash spills down the drain.
Handling: Always handle within a glove box or fume hood with rigorous moisture control. Open only with precaution—unhurried, steady hands, away from incompatible substances.
Storage: Store trims in sealed, moisture-proof containers. Keep locked storage away from water, alcohols, acids, amines, and oxidizers. Even the slightest dampness in the air can spark a mess. Regular checks for leaks or pressure buildup prevent both minor accidents and major disasters.
Engineering Controls: Maintain active ventilation and air filtration near the chemical’s working area. Automated moisture alarms offer extra reassurance.
Personal Protective Equipment: Workers choose chemical-resistant gloves, safety goggles, full face shields, and lab coats. Respiratory protection stands by for every process outside an inert atmosphere.
Hygiene Measures: Wash hands and exposed skin after every task. Remove protective gear with care to dodge accidental contact or contamination.
Form: Liquid
Color: Clear to faintly yellow
Odor: Strong, unpleasant, and chemical
Melting/Freezing Point: Remains in liquid phase under standard lab conditions; no precise public data available
Boiling Point: Not widely published; volatility demands that storage avoids high temperatures
Solubility: Not soluble in water; decomposes violently
Reactivity: Erupts with moisture, acids, and oxidizers.
Stability: Only stable under inert atmosphere and dry conditions. Exposed to air or humid environments, decomposition speeds up.
Incompatible Materials: Water, alcohols, acids, amines, strong oxidizers
Hazardous Decomposition Products: Hydrogen bromide, methyl bromide, aluminum oxides—all unpleasant at best and dangerous at worst.
Acute Effects: Skin and eye contact burns quickly and deeply. Inhalation leads to severe irritation, coughing, and difficulty breathing.
Chronic Effects: Prolonged or repeated exposure may result in tissue damage, bronchial problems, and potentially long-term scarring of respiratory organs.
Routes of Exposure: Inhalation, skin absorption, ingestion, and splash to eyes all invite significant harm.
Other Health Hazards: No confirmed cancer risks reported in public studies, but data remains limited because long-term human exposure rarely happens outside accident cases.
Aquatic Toxicity: Highly toxic for fish and aquatic species. Discharge into waterways must be strictly controlled or avoided entirely.
Persistence and Degradability: The compound and its by-products linger in the environment for long periods.
Mobility in Soil: Once in the soil, the substance migrates, risking wider contamination.
Other Ecological Hazards: Water-reactivity intensifies damage, generating additional hazardous substances in real-world spills.
Waste Handling: Take spent or unused material to specialized chemical disposal facilities. Incineration under strict environmental controls offers a last line of defense against release.
Contaminated Packaging: All bottles, gloves, and tools exposed to this chemical demand separate collection and safe disposal.
Recommended Approach: Teams log every disposal and avoid landfill burial or drain dumping.
UN Number: Classified under hazardous chemicals for transport—those using international road, sea, or air routes need to follow strict labelling, secure containers, and training of drivers and handlers.
Packing Method: Sealed metal or glass bottles, packed in dry, sturdy outer containers.
Major Risks: Package leaks, accidental water contact, and poor ventilation inside vehicles threaten both the shipment and everyone in the area. Emergency response training during shipping remains non-negotiable.
Workplace Restrictions: Most countries put tight restrictions around purchase, handling, and disposal. Only licensed professionals handle this chemical without legal trouble.
Labeling: All packages must carry hazard and precautionary statements in line with local and international regulations.
Reporting Requirements: Any major spill or accidental release must be reported to environmental and workplace health authorities without delay.
Worker Training: Regulations demand all staff be trained in safe use, emergency response, and proper use of personal protection equipment.
