Accidental Release Measures

Personal Precautions: Use personal protective equipment including gloves, goggles, and a lab coat.
Environmental Precautions: Prevent large quantities from entering waterways, inform authorities in case of significant spillage.
Methods for Cleaning Up: Contain and collect spillage with inert absorbent, store in suitable closed containers for disposal, ventilate area, wash spill site after material pickup.

Handling and Storage

Handling: Wear suitable protective clothing and gloves, avoid inhalation or contact with skin or eyes, use only in well-ventilated areas.
Storage: Store in a tightly closed container, away from incompatible substances (strong oxidizing agents, strong bases), keep in dry, cool, and well-ventilated space, protect from direct sunlight, segregate from food and beverages, keep out of reach of children and unauthorized personnel.

Toxicological Information

Acute Toxicity: Not thoroughly studied; expected to have low acute toxicity based on chemical structure similarity to choline and tosylate salts.
Skin Corrosion/Irritation: Contact may cause irritation or redness.
Serious Eye Damage/Irritation: Causes eye irritation; risk of serious damage is low for brief contacts but continuous exposure increases risk.
Respiratory Sensitization: Dust may cause mild irritation of respiratory tract.
Chronic Effects: No data for long-term exposure; avoid repeated or prolonged contact.
Other Effects: No known carcinogenic, mutagenic, or reproductive toxicity effects for this compound.

Ecological Information

Ecotoxicity: Data not available; not expected to be hazardous to aquatic organisms in small quantities but prevent material from entering water systems as a precaution.
Persistence and Degradability: Expected to be biodegradable based on structure.
Bioaccumulative Potential: Low potential for bioaccumulation; water-soluble, likely to be excreted.
Mobility in Soil: High water solubility suggests mobility in soil; may leach into groundwater if released.
Other Adverse Effects: Limited data; minimizing environmental release is best practice.

Disposal Considerations

Waste Disposal: Dispose of as hazardous or chemical waste per local, state, federal regulations.
Contaminated Packaging: Wash thoroughly and recycle or dispose of as chemical waste.
