Common Names: Cu(EDA) Solution, Copper(II) ethylenediamine complex
Recommended Use: Analytical chemistry, cellulose dissolution, laboratory reagent
Supplier Information: Distributed by established chemical suppliers in laboratory and industrial sectors
Emergency Contact: Local Poison Control Center or supplier-provided emergency response number
GHS Classification: Acute Toxicity (Oral, Dermal, Inhalation), Skin Corrosion/Irritation, Eye Damage
Signal Word: Danger
Hazard Statements: Harmful if swallowed, skin contact, or inhaled; may cause burns to skin and eyes; can provoke respiratory irritation
Pictograms: Corrosive, Exclamation Mark
Precautionary Statements: Avoid breathing vapors; use proper PPE; keep out of reach of children; wash hands and exposed areas thoroughly after handling; avoid release to the environment
Chemical Name: Copper(II) Ethylenediamine Complex
Main Constituents: Copper(II) sulfate or chloride (approx 5–15%), Ethylenediamine (15–25%), Water (balance), traces of stabilizers
CAS Numbers: Copper compounds (7758-99-8 or 7447-39-4), Ethylenediamine (107-15-3), Water (7732-18-5)
Inhalation: Remove from exposure, provide fresh air, seek medical attention for persistent cough or breathing difficulty
Skin Contact: Remove contaminated clothing, rinse thoroughly with water for at least 15 minutes, seek medical advice if irritation persists
Eye Contact: Rinse cautiously with clean water for at least 15–20 minutes, hold eyelids apart, seek medical assistance immediately
Ingestion: Do not induce vomiting; rinse mouth with water, call medical professional or poison control immediately
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide extinguishers
Fire Hazards: Non-flammable in normal settings, but decomposition releases toxic fumes (nitrogen oxides, copper oxides, ammonia)
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective clothing
Specific Hazards Arising from Chemical: Fumes may irritate respiratory tract; fire runoff may contaminate waterways
Personal Precautions: Wear impermeable gloves, goggles, and laboratory coat; assure adequate ventilation
Environmental Precautions: Prevent large spills from entering drains, water sources or soil
Clean-up Methods: Neutralize with dilute acid if designated safe, collect with absorbent material like sand or vermiculite, transfer to sealed chemical waste containers, clean area with plenty of water
Reporting Requirements: Inform local authorities about major releases per regulatory obligations
Handling: Use in a chemical fume hood or well-ventilated area; avoid direct contact with skin and eyes; never eat, drink, or smoke during handling
Storage Conditions: Store in tightly closed containers made of compatible materials (HDPE, glass); label storage; keep away from strong acids and oxidizers
Temperature Requirements: Room temperature (keep away from freezing conditions and direct sunlight)
Incompatibilities: Strong acids, oxidizing agents, halogenated solvents
Exposure Limits: OSHA PEL for copper (as fume, dust): 1 mg/m3; Ethylenediamine: 10 ppm TWA
Engineering Controls: Use chemical hoods, exhaust systems, and safeguards against leaks
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), splash-proof goggles or face shield, lab coat, closed-toe shoes; respiratory protection (organic vapor cartridge, particulate respirator) for airborne concentrations above recommended limits
Hygiene Recommendations: Wash hands and face before breaks and after handling; remove contaminated clothing and wash separately
Appearance: Deep blue liquid
Odor: Ammoniacal
pH: Approximately 12–13 (strongly basic)
Melting Point: Below 0°C
Boiling Point: Above 100°C; decomposition occurs before boiling
Solubility: Miscible with water
Vapor Pressure: Low at room temperature
Density: 1.03–1.12 g/cm³
Viscosity: Slightly more viscous than water
Chemical Stability: Stable under recommended storage conditions
Reactivity: Reacts vigorously with strong acids, acid chlorides, and some metals
Conditions to Avoid: Avoid contact with incompatible materials, excessive heat, and freezing temperatures
Hazardous Decomposition Products: Ammonia, nitrogen oxides, copper oxides
Polymerization: Does not self-polymerize
Routes of Exposure: Skin and eye contact, inhalation, ingestion
Acute Effects: Causes severe irritation and chemical burns to eyes, mucous membranes, skin
Chronic Effects: Prolonged exposure may lead to dermatitis, respiratory sensitization, copper accumulation in body tissues
Toxicity Data: Ethylenediamine (oral LD50, rat): 1,600 mg/kg; Copper salts: lower LD50; may produce toxic cumulative effects
Symptoms: Burning, redness, blistering on skin; eye pain or damage; cough, sore throat, dizziness from inhalation; nausea, vomiting, diarrhea if swallowed
Aquatic Toxicity: Highly toxic to aquatic life; copper ions disrupt aquatic ecosystems
Persistence and Degradability: Copper stays in soil and water, does not degrade quickly
Bioaccumulation: Copper can accumulate in plants or animals, impacting food chains
Mobility in Soil: Moderate depending on organic content, can leach to water sources
Additional Ecological Hazards: Ethylenediamine has high mobility and may persist under certain conditions; take special care after spills
Disposal Methods: Treat as hazardous chemical waste; contact authorized chemical disposal companies for collection
Container Disposal: Triple-rinse, puncture, clearly label as hazardous before discarding according to local and national rules
Do Not: Release product into drains or natural environments strict disposal laws in effect
Precautions: Follow all MSDS and local environmental safety recommendations on disposal procedures
