Reproductive Toxicity: Not tested but structurally related substances have not shown reproductive effects
STOT – Single or Repeated Exposure: No data available; avoid repeated exposure to minimize potential risk
Aspiration Hazard: Not classified as an aspiration toxicant
Ecotoxicity: Toxic to aquatic life with long-lasting effects, imidazolium-based ionic liquids tend to bioaccumulate in sediment and soil
Persistence and Degradability: Low biodegradability has been reported for related compounds, may persist in the environment
Bioaccumulative Potential: Possibility of moderate to high bioaccumulation in aquatic species
Mobility in Soil: Potential for leaching into groundwater if not properly contained; movement predominately dependent on soil type and local water content
Other Adverse Effects: Lack of sufficient research on long-term ecological impacts for this chemical class
Waste Treatment Methods: Collect and store waste in clearly marked, tightly sealed chemical-resistant containers; keep segregated from incompatible waste streams
Disposal of Product: Disposal must follow local, regional, and national regulations for hazardous chemical waste; incineration in a licensed facility preferred, avoid landfill disposal
Disposal of Contaminated Packaging: Triple rinse and dispose of via licensed waste handler, small containers may require chemical neutralization before disposal; do not allow residues to enter drains, soil, or water sources
