Solubility:

Not miscible with water, easily soluble in ether and acetone, soluble in carbon tetrachloride

Precautions:

1. Operation and storage methods: Keep away from fire, place in a closed container, and store in a cool and dry place. Keep refrigerated (Store below 4°C/39°F.)

2. Emergency treatment and disposal methods: 1. Leakage emergency treatment: Use inert materials (sand, etc.) to absorb the leaked medicine, place it in a specific container, and use fire-proof tools to transfer flammable materials.

3. Protective measures: engineering control: tightly closed and provide adequate local exhaust. Provide safety shower and eyewash equipment. Eye protection: wear chemical safety glasses. Body protection: Wear protective clothing to avoid skin contact. Respiratory protection: When you may be exposed to its vapor, you should wear a self-priming filter gas mask (full face mask). In emergency rescue or evacuation, it is recommended to wear isolated respirators.

4. First aid measures: Eyes: lift the eyelids and rinse with running water or normal saline. Seek medical attention. Skin: Take off contaminated clothing immediately and rinse with plenty of running water. Seek medical attention. Ingestion: Do not vomit, rinse mouth with water, and seek medical attention. Inhalation: Move to a well-ventilated place. If breathing stops, give artificial respiration. If breathing is difficult, take oxygen in time. Seek medical attention.
