Ingestion: Rinse mouth, do not induce vomiting, give water only if person is conscious, seek urgent medical care
General Advice: Show this datasheet to treating physician, monitor for respiratory difficulties or allergic reactions
Suitable Extinguishing Media: Water spray, dry chemical, CO2, foam; avoid high-pressure streams aiming directly at product
Specific Hazards: Chloride-containing vapors, nitrogen oxides may release if exposed to fire; product may decompose under heating producing toxic gases
Protective Equipment: Full protective gear, self-contained breathing apparatus for fire service personnel
Special Procedures: Remove containers from fire area if safely possible, cool containers exposed to flames with water
Combustibility: Low to moderate; does not sustain combustion easily but may burn under intense heat
Personal Precautions: Wear gloves, goggles, impermeable clothing, provide adequate ventilation, evacuate area if large spill occurs
Environmental Precautions: Prevent entry into drains, soil, water courses; notify appropriate authorities in case of significant release
Containment: Absorb using inert material (sand, vermiculite), transfer to suitable labeled waste containers
Cleanup Methods: Avoid creating dust, scoop up solid or viscous material carefully, ventilate area thoroughly
Decontamination: Wash spill site with detergent and water after removal of bulk material
Handling: Keep containers tightly sealed, avoid contact with moisture, minimize contact time, use designated chemical areas, wash hands thoroughly after handling
Storage: Store in cool, dry, well-ventilated location away from incompatible materials (strong oxidizers, acids, bases), prevent static discharge, keep away from sources of ignition
Storage Containers: Use corrosion-resistant, airtight containers; check regularly for signs of leakage or deterioration
Additional Advice: Label containers clearly, keep out of reach of unauthorized personnel, store at above freezing to prevent crystallization in certain grades
Engineering Controls: Use local exhaust ventilation, chemical fume hood, or other engineering means in laboratory and production settings
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile, butyl rubber), safety goggles, laboratory coat, closed footwear; in large-scale operations, use face shield and chemical apron
Respiratory Protection: Approved respirators recommended when working with fine particulates, dusts, or heated product, especially in poorly ventilated spaces
Hygiene Measures: Wash hands, arms, and face thoroughly before eating, drinking, or smoking after handling substance
Possible Exposure Limits: No established occupational exposure limit, minimize airborne dust and contact through best practices
Appearance: White to off-white crystalline solid or viscous liquid
Odor: Faint, slightly ammoniacal odor
pH (aqueous solution): Near neutral to slightly basic (7-9 for 10% solution)
Melting Point: 47–59°C (varies by purity and hydration)
Boiling Point: Decomposes before boiling
Flash Point: >150°C (closed cup; not easily ignited under normal conditions)
Solubility: Highly soluble in water and many organic solvents (methanol, ethanol, DMSO, etc.)
Vapor Pressure: Negligible at room temperature
Density: 1.07–1.11 g/cm³ at 20°C
Viscosity: High (liquid form); increases with decreasing temperature
Chemical Stability: Stable under recommended conditions, degrades slowly if exposed to strong acids, bases, or elevated temperatures
Incompatible Materials: Strong oxidizers (peroxides, chlorates), reducing agents, acids, alkali metals
Hazardous Decomposition Products: Chlorine ions, nitrogen oxides, imidazole derivatives, possible toxic halogen chloride gases under thermal decomposition
Reactivity Alerts: Moisture may promote hydrolysis, avoid contact with reactive chemicals
Polymerization Risk: Does not polymerize under normal handling and storage conditions
Acute Toxicity: Limited animal testing; oral LD50 (rat) not established, estimated above 500 mg/kg; skin exposure causes moderate irritation
Skin Corrosion/Irritation: Demonstrates irritating properties; may cause contact dermatitis on repeated use
Eye Damage/Irritation: Strongly irritating or damaging to eyes on direct contact
Respiratory Effects: Inhalation of dust may irritate mucous membranes and airways
Allergy/Sensitization: Possible risk of sensitization from repeated exposure
Carcinogenicity: No data shows carcinogenic potential; not listed by IARC, NTP, or OSHA
Other Health Effects: High doses may impact kidney and liver function based on imidazole analogs, monitor exposed individuals for symptoms
Ecotoxicity: Harmful to aquatic organisms, potential for bioaccumulation low but acute toxicity reported in fish and invertebrates at moderate concentrations
Persistence and Degradability: Partially biodegradable; breakdown products may include persistent imidazole derivatives
Mobility in Soil: High solubility creates risk for movement through soil into water bodies
Aquatic Impact: Elevated concentrations harmful to microflora and small aquatic species; restrict release into waterways
Other Environmental Effects: Avoid large scale disposal to sewers, surface water, or soil
Waste Methods: Collect unused or spilled material in suitable containers for chemical waste disposal following local, national, and international regulations
Incineration: Permitted at licensed facility with flue gas scrubbing and neutralization
