Chemical Name: Copper(II) Nitrate
CAS Number: 3251-23-8
Concentration: Typically greater than 98% in technical grade product
Other Components: May contain trace impurities or stabilizers, percentage depends on batch
Inhalation: Move to fresh air immediately. Provide oxygen or artificial respiration if breathing has stopped. Seek prompt medical attention.
Skin Contact: Remove contaminated clothing. Rinse skin with water for at least 15 minutes. Contact a physician if irritation develops.
Eye Contact: Flush eyes with water for 15 minutes, lifting eyelids occasionally. Call a medical professional promptly.
Ingestion: Rinse mouth with water, do not induce vomiting. Drink water if conscious. Immediate attention from medical personnel is necessary due to toxicity risk.
Note to Physician: Treat symptomatically, monitor for kidney and liver function anomalies with significant exposure.
Suitable Extinguishing Media: Use water spray, fog or foam. Dry chemical powder or carbon dioxide generally ineffective since substance supports combustion.
Unsuitable Extinguishing Media: Never use dry chemical extinguishers alone for oxidizers; avoid halogenated agents.
Fire Hazards: Strong oxidizer, increases risk of fire. May explode or intensify fire in contact with combustible materials.
Decomposition Products: Highly toxic gases, including nitrogen oxides and copper oxides, form under fire conditions.
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective clothing required. Remove containers from area if safe.
Personal Precautions: Evacuate unnecessary personnel. Wear appropriate PPE, including gloves and eye protection.
Environmental Precautions: Prevent entry into drains or watercourses. Notify authorities if significant environmental contamination occurs.
Clean-up Methods: Sweep up spilled material without creating dust and place in suitable container for disposal. Wash spill site thoroughly with water after clean-up. Use spark-proof tools. Ventilate area.
Safe Handling: Wear protective gear and operate in well-ventilated areas. Avoid generating dust. Keep away from sparks, flames, and incompatible materials, especially flammable substances.
Storage: Store in tightly closed containers in a cool, dry, and well-ventilated location. Segregate from reducing agents, organic materials, and acids. Store away from heat sources and out of sunlight.
Other Precautions: Regularly check containers for corrosion and leaks. Ensure labels remain visible and legible.
Engineering Controls: Use local exhaust ventilation or chemical fume hood to reduce airborne concentrations.
Control Parameters: Copper (as Cu) ACGIH TLV: 1 mg/m3 (dust and mist), OSHA PEL: 1 mg/m3. Nitrate does not have an individual exposure limit, but good general ventilation is recommended.
Personal Protective Equipment: Wear chemical-resistant gloves (such as nitrile or neoprene), safety goggles, and laboratory coat. In dusty environments, use approved dust masks or respirators.
Hygiene Practices: Wash hands before eating or drinking, and after handling material. Remove contaminated clothing and clean before reuse.
Appearance: Blue-green, crystalline solid or prismatic crystals
Odor: No characteristic odor
Odor Threshold: Not established
pH: Acidic solution
Melting Point: 114°C (decomposes)
Boiling Point: Decomposes before boiling
Flash Point: Not flammable
Explosive Properties: Acts as an oxidizer, enhances combustion rather than explodes
Vapor Pressure: Negligible at room temperature
Solubility: Soluble in water, ethanol
Density: 2.32 g/cm3 (anhydrous)
Partition Coefficient (n-octanol/water): Not available
Auto-ignition Temperature: Not self-igniting
Decomposition Temperature: >114°C
Chemical Stability: Stable under recommended storage conditions. Moisture absorption can accelerate decomposition.
Reactivity: Reacts with reducing agents, combustible and organic materials.
Incompatible Materials: Reducing agents, powdered metals, organic materials, strong acids, and flammable substances.
Decomposition Products: Copper oxides, nitrogen oxides, and nitrous gases form on heating or in fire conditions.
Hazardous Reactions: Contact with strong reducing agents may cause fire and explosion hazard.
Likely Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Effects: Inhalation may cause respiratory irritation, coughing, and shortness of breath. Swallowing leads to abdominal pain, nausea, vomiting, and diarrhea; large doses affect liver and kidneys.
Chronic Effects: Prolonged or repeated exposure may result in skin sensitization, dermatitis, or harmful effects on the liver and kidneys.
Symptoms: Eye reddening, pain, blurred vision. Skin burns or irritation. Gastrointestinal distress.
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA.
Mutagenicity / Reproductive Toxicity: No conclusive evidence from available data.
LD50 Oral (rat): 940 mg/kg; inhalation and dermal LD50 values not well established.
Aquatic Toxicity: Very toxic to aquatic organisms; long-term effects on aquatic environments. Copper ions bioaccumulate and disrupt aquatic ecosystems.
Fate in Environment: Persistent, not readily biodegradable in water or soil.
Mobility: Highly mobile in water, leaching potential in soil especially under low pH conditions.
Other Adverse Effects: Copper nitrate release threatens fish, aquatic invertebrates, and may contaminate drinking water. Spills need rapid reporting to environmental regulators.
Waste Treatment Methods: Dispose as hazardous waste through a licensed facility.
Containment: Collect in sealed, corrosion-resistant containers.
Disposal of Contaminated Packaging: Empty containers may retain product residues; treat as hazardous waste.
Do Not: Discharge into waterways, sewers, or unrestricted landfill. Consult local, state, and federal environmental regulations for disposal guidance.
