Chemical: Trioxylmethylphosphonium Bromide CAS Number: 4964-50-5 Concentration: >98% Impurities: Contains trace amounts of other phosphonium compounds, water content generally less than 1% Molecular Weight: 247.97 g/mol
Inhalation: Move person to fresh air, provide oxygen or artificial respiration as necessary, seek immediate medical attention Skin Contact: Remove contaminated clothing, rinse skin with plenty of water for at least 15 minutes, seek medical advice for burns Eye Contact: Rinse cautiously with water for at least 15 minutes, lift eyelids occasionally, remove contact lenses if present and easy to do, get medical attention right away Ingestion: Rinse mouth thoroughly, do not induce vomiting, seek medical help immediately Most Important Symptoms/Effects: Burning sensation, coughing, headache, severe irritation to all exposed tissue
Suitable Extinguishing Media: Dry chemical, carbon dioxide (CO₂), alcohol-resistant foam, do not use water jet Specific Hazards: May emit toxic fumes of phosphorus oxides, bromides, and carbon oxides during decomposition Protective Equipment: Firefighters should use self-contained breathing apparatus and chemical-resistant protective clothing Special Precautions: Evacuate area, contain runoff to prevent contamination of water sources Combustion Products: Phosphorus oxides, methyl bromide, hydrogen bromide
Personal Protection: Wear full chemical-resistant gloves, safety goggles, lab coat, and use adequate ventilation Environmental Precautions: Prevent further leakage or spillage if safe to do so, prevent entry into drains, sewers, or waterways Containment and Cleanup: Sweep up and collect spilled material with non-sparking tools, avoid creating dust, store in suitable closed container for disposal, wash spill area with plenty of water and detergent Decontamination: Neutralize residues with dilute sodium bicarbonate (if safe)
Handling: Work in a chemical fume hood, minimize dust generation and accumulation, use only non-sparking tools, avoid skin and eye contact Storage: Store tightly closed in a cool, dry, well-ventilated area, protect from moisture, segregate from strong acids and bases, keep away from reactive chemicals and combustible materials Incompatible Materials: Strong oxidizers, water, bases, strong reducing agents Specific End Uses: Chemical research, synthesis, not for food or drug use
Exposure Limits: No established OSHA or ACGIH limits for Trioxylmethylphosphonium Bromide; minimize workplace concentrations as much as possible Engineering Controls: Use chemical fume hood, laboratory ventilation systems, minimize dust creation Personal Protective Equipment: Chemical-resistant gloves (nitrile or rubber), safety goggles or face shield, laboratory coat, appropriate respiratory protection in case of dust formation Hygiene Practices: Wash hands and face thoroughly after handling, do not eat or drink while handling, launder contaminated clothing
Appearance: White or off-white crystalline powder Odor: Odorless or faint chemical smell Odor Threshold: Not available pH: Not applicable Melting Point/Freezing Point: 120–124 °C Boiling Point: Decomposes above melting point Flash Point: Not applicable (solid) Evaporation Rate: Not applicable Flammability: Not classified as flammable, but combustible in presence of ignition sources Vapor Pressure: Negligible at room temperature Vapor Density: Not applicable Relative Density: 1.65 (approximate) Solubility: Soluble in water and polar organic solvents Partition Coefficient (n-octanol/water): Not determined Auto-Ignition Temperature: Not determined Decomposition Temperature: >120 °C Viscosity: Not applicable
Chemical Stability: Stable under recommended storage conditions, sensitive to moisture and high temperatures Possibility of Hazardous Reactions: Reacts with strong bases, acids, or oxidizers to produce hazardous products Conditions to Avoid: Heat, moisture, direct sunlight, sources of ignition Incompatible Materials: Strong oxidizing agents, water, strong bases, reducing agents Hazardous Decomposition Products: Methyl bromide, phosphorus oxides, carbon oxides
Likely Routes of Exposure: Inhalation, ingestion, eye/skin contact Acute Effects: Harmful if swallowed, can cause burns to digestive and respiratory tracts, severe skin and eye damage Chronic Effects: No adequate data for chronic toxicity, prolonged or repeated exposure may aggravate asthma or skin disorders Carcinogenicity: No data available, not listed by IARC/OSHA/ACGIH Mutagenicity: No reliable data Reproductive Toxicity: Data not sufficient Signs and Symptoms of Exposure: Burning pain, redness, watering eyes, blistering skin, shortness of breath, cough LD50 (estimated): Not well defined for humans, estimated oral-rat LD50 <500 mg/kg
Ecotoxicity: Toxic to aquatic life, may cause long-lasting harmful effects in the environment Persistence and Degradability: Not readily biodegradable, persists under typical environmental conditions Bioaccumulative Potential: Low potential based on molecular properties, but potential for bioaccumulation not fully studied Mobility in Soil: High mobility in water, may leach into groundwater Other Adverse Effects: Avoid uncontrolled release, likely to disrupt aquatic organisms and microbial populations
Waste Treatment Methods: Treat as hazardous chemical waste, use high-temperature incineration at licensed facility Disposal of Containers: Rinse empty containers with water, dispose in accordance with local/regional/national regulations for hazardous materials Precautions: Avoid release to environment, do not dispose of with general household refuse Contaminated Packaging: Destroy after thorough cleaning, follow hazardous waste protocols
