Chemical Identity: Tetramethylammonium Nitrate
Concentration: Typically ranges between 95% to 99% pure
Impurities: Trace water, minor organic or inorganic contaminants from manufacturing
Molecular Weight: 136.15 g/mol
Component Type: Single substance
Inhalation: Move person to fresh air. Seek medical attention if symptoms develop. Monitor breathing and provide oxygen if difficulty occurs.
Skin Contact: Remove contaminated clothing. Wash skin with plenty of soap and water. If irritation occurs or persists, get medical advice.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Seek immediate medical attention for any persistent irritation or vision problems.
Ingestion: Rinse mouth with water. Do not induce vomiting. Get immediate medical assistance. Never give anything by mouth to a person who is unconscious.
Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Do not use straight streams of water on burning material.
Special Hazards: Product acts as a strong oxidizer, increasing fire hazard. Decomposes on heating to produce toxic nitrogen oxides.
Protective Equipment: Firefighters require full protective gear and self-contained breathing apparatus.
Firefighting Instructions: Evacuate area. Move containers from fire area if it can be done without risk. Use water spray to keep fire-exposed containers cool.
Personal Precautions: Avoid inhaling dust or vapor. Use appropriate personal protective equipment. Eliminate sources of ignition.
Environmental Precautions: Prevent run-off into drains, watercourses, and soil. Notify authorities for significant spills.
Containment and Cleanup: Sweep up material without creating dust. Place in a suitable container for disposal. Wash spill site after material pickup is complete. Use a neutralizing agent if appropriate for the quantity spilled.
Safe Handling: Handle in a well-ventilated area. Avoid direct contact with skin, eyes, and clothing. Use spark-proof tools and explosion-proof equipment. Do not generate dust.
Storage Conditions: Store in a cool, dry, well-ventilated place. Keep container tightly closed and away from incompatible materials including reducing agents, combustible substances, strong acids, and bases.
Incompatibilities: Avoid storage near organic materials, strong oxidizing agents, metallic powders, and moisture.
Special Precautions: Ensure all containers are properly labeled. Ground and bond containers when transferring material. Regularly check containers for leaks or degradation.
Engineering Controls: Operate under chemical fume hood with exhaust ventilation. Use explosion-proof electrical fixtures where powder handling occurs. Provide local eye wash and emergency shower facilities.
Personal Protection: Wear chemical splash goggles, impermeable gloves, lab coat, and face shield when risk of splashing exists. Use NIOSH-approved respirators for dust or vapor exposure. Do not eat, drink, or smoke in work area.
Appearance: White crystalline solid
Odor: Little to none
Melting Point: 125°C to 130°C
Boiling Point: Decomposes before boiling
Solubility: Highly soluble in water, soluble in methanol and ethanol
Density: About 1.1 g/cm³
pH (1% solution): Slightly basic
Vapor Pressure: Negligible at room temperature
Viscosity: Not applicable
Flash Point: Not flammable as a solid, strong oxidizer
Decomposition Temperature: Above 130°C, releases toxic nitrogen oxides
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Acts as a strong oxidizer, reacts violently with reducing agents, combustible materials, strong acids
Hazardous Decomposition Products: Nitrogen oxides, methylamines, carbon oxides, in combustion or decomposition
Polymerization: Not known to polymerize
Other: Sensitive to heat, may detonate under conditions of severe mechanical shock or when heated with incompatible materials
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Effects: Toxic if swallowed, can irritate respiratory tract, eyes, skin
Chronic Effects: Prolonged or repeated exposure may affect organs, especially nervous system
Symptoms: Nausea, vomiting, headache, suffocation sensation, skin redness, eye burns
Toxicity Data: Oral LD50 (rat): approximately 200-500 mg/kg; Dermal LD50 (rabbit): not fully established
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Other Risks: No strong evidence for mutagenic, teratogenic, or reproductive toxicity at standard exposure levels, but precaution is crucial due to potent toxicity
Aquatic Toxicity: Very toxic to aquatic life due to nitrate content and methylammonium ion
Mobility in Soil: High solubility means migration through soil and potential groundwater contamination
Persistence/Degradability: Nitrate ion can persist; methylammonium can be broken down by microbes in water and soil, but rate is slow in cold environments
Bioaccumulation: Low potential for bioaccumulation, rapid dilution in moving water systems
Other Effects: Eutrophication risk if material enters water bodies due to high nutrient load
Waste Treatment Methods: Handle as hazardous waste according to local, regional, or national regulations. Small amounts can be diluted and neutralized with care by qualified personnel.
Disposal Containers: Use tightly sealed, clearly labeled hazardous waste containers. Do not dispose with general waste.
Special Precautions: Avoid release to sewers or natural waterways. Consult waste disposal specialist for large quantities or contaminated packaging.
Contaminated Packaging: Rinse thoroughly, then dispose as hazardous waste in accordance with regulations
