Chemical Name: 1,3-Dimethylimidazolium Iodide
Purity: Greater than 98% common in laboratory grade samples
Impurities: Trace residual solvents such as acetonitrile or water <0.5%; unreacted dimethylimidazole typically below 0.1%
Stabilizing Additives: None typically added for this chemical; ensure container free from incompatible chemicals like strong bases or oxidizers.
Inhalation: Remove victim to fresh air. If not breathing, perform artificial respiration. If symptoms like coughing or difficulty breathing persist, medical attention is necessary.
Skin Contact: Rinse thoroughly with soap and water for 15 minutes. Contaminated clothing should be removed and washed before reuse. Seek medical help if redness or irritation develops.
Eye Contact: Hold eyelids apart and flush eyes with water for at least 15 minutes, lifting eyelids occasionally. Immediate physician attention if irritation continues.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by qualified medical personnel. If exposed to large amounts or if symptoms occur, go to the nearest emergency room.
Suitable Extinguishing Media: Use water spray, dry chemical powder, carbon dioxide, or foam. Avoid high-pressure streams that could spread the chemical.
Unsuitable Extinguishing Media: Avoid direct water jet on the product if spilled because it may spread contamination.
Hazards from Combustion: Iodine vapors, nitrogen oxides, carbon oxides, possible imidazole derivatives. Smoke from burning can cause respiratory tract irritation.
Special Protective Equipment: Firefighters must wear full protective gear and a self-contained breathing apparatus. Remove containers from fire area if safe.
Personal Precautions: Wear appropriate protective gear: gloves, lab coat, chemical safety goggles, and avoid direct contact. Use a respirator if dust or vapor cloud forms.
Environmental Precautions: Prevent product from entering drains, waterways, or soil. Notify authority if significant spill occurs.
Containment Methods: Collect spillage using non-sparking tools and place in a sealed container for disposal.
Clean-Up Procedures: Ventilate area. Thoroughly clean affected surface using water and detergent. Wash skin thoroughly after handling.
Handling: Work in a well-ventilated place or under a fume hood. Always use proper personal protective equipment. Avoid inhalation of dust or vapors. No open food or drink should be present where chemical is used.
Storage Conditions: Store in tightly sealed containers, away from moisture, strong oxidizers, and bases. Keep in a cool, dry location, preferably locked or limited access if possible.
Incompatibilities: Keep away from strong oxidizing agents, acids, and alkalis due to potential exothermic reactions.
Special Considerations: Label storage area clearly. Inventory should be checked regularly for leaks or degradation.
Occupational Exposure Limits: No established limits for this compound. Use general controls like minimizing dust and vapor levels.
Engineering Controls: Use chemical fume hood, local exhaust, or ventilation to keep airborne levels below nuisance levels.
Personal Protective Equipment: Safety goggles or face shield, chemical-resistant gloves such as nitrile, lab coat or apron.
Respiratory Protection: NIOSH-approved respirator if airborne concentrations increase. Avoid contact lenses in lab.
Hygiene: Wash hands thoroughly after handling and before eating or drinking.
Appearance: White to off-white crystalline powder
Molecular Weight: 240.05 g/mol
Odor: Odorless or mild chemical
Melting Point: 145-150°C
Boiling Point: Decomposes before boiling
Solubility: Highly soluble in water, methanol, ethanol; less soluble in non-polar solvents
Vapor Pressure: Negligible
pH: Slightly acidic to neutral in water
Density: Approximately 1.7 g/cm³
Flash Point: Not considered flammable under normal conditions.
Chemical Stability: Stable at room temperature and in closed containers. Avoid exposure to moisture to prevent degradation.
Possible Reactions: Decomposes on strong heating, releasing toxic fumes of iodine, nitrogen oxides, and carbon monoxide
Conditions to Avoid: High temperatures, humidity, sources of ignition, and exposure to strong acids or bases
Incompatible Materials: Oxidizing agents, strong bases, strong acids
Hazardous Decomposition Products: Iodine, carbon oxides, nitrogen-containing gases under fire or decomposition.
Acute Toxicity: Data limited, but based on structure, expected to cause minor respiratory or digestive irritation with large exposures. Dermal LD50 estimated above 2000 mg/kg in rats.
Chronic Toxicity: Prolonged exposure could impact thyroid functions due to the presence of iodide ions. No conclusive data on carcinogenicity, but routine lab safety reduces unnecessary risk.
Routes of Exposure: Eye and skin contact, inhalation, ingestion
Symptoms: May include redness, itching, headache, coughing, nausea. Higher doses could affect pulse or cause dizziness.
Sensitization: Potential for skin sensitization after repeated exposure.
Other Information: No evidence of reproductive toxicity or mutagenicity in available studies.
Toxicity: Harmful to aquatic life with long-lasting effects. Avoid uncontrolled release to natural water systems.
Persistence and Degradability: Partial degradation in environment, but iodide portion may persist.
Bioaccumulation: No evidence to suggest significant accumulation in aquatic or terrestrial organisms.
Mobility: Mobile in water due to high solubility.
Additional Notes: The chemical should always be disposed of with maximum care, keeping laboratory and industrial waste separated from regular municipal systems.
Safe Handling: Place waste in a properly labeled chemical waste container. Caps must fit tightly to prevent leaks or exposure.
Disposal Method: Dispose at approved hazardous waste facility, following all local and national regulations. Do not flush or pour into drains, sewers, or natural waters.
Contaminated Packaging: Clean or triple rinse containers before disposal or recycling, as regulations dictate.
Special Instructions: Coordinate disposal through your institution’s Environmental Health & Safety office for best practices.
