Acute Toxicity: Expected to be harmful if swallowed or inhaled; may cause gastrointestinal discomfort or vomiting
Skin Corrosion/Irritation: Causes skin irritation upon direct contact
Eye Damage/Irritation: Causes serious eye irritation or damage
Respiratory or Skin Sensitization: Not classified, but repeated exposure may induce sensitization in susceptible individuals
Long-Term Effects: No data for carcinogenicity, mutagenicity, or reproductive toxicity available for this compound
Other Effects: Prolonged or repeated skin exposure may cause dermatitis; persons with allergies may develop reactions
Environmental Toxicity: Very toxic to aquatic life, may cause long lasting adverse effects in the environment
Bioaccumulation: No data available, but structure suggests potential for bioaccumulation due to alkyl chains
Persistence and Degradability: Not readily biodegradable under standard conditions; ionic liquids can persist in the environment
Mobility in Soil: Likely to have low mobility due to ionic nature, but can pose risk to aquatic systems upon runoff
Other Adverse Effects: Spillage or improper disposal can harm aquatic organisms and disrupt biological wastewater treatment
Product Disposal: Dispose of only through hazardous chemical waste channels; incineration under controlled conditions is preferred
Container Disposal: Triple-rinse, then offer clean containers for local recycling or reconditioning if permitted by local regulations; otherwise, treat as hazardous waste
