Safety information

Hazard overview:

May be irritating to the skin and eyes, and inhalation or accidental swallowing may cause respiratory or digestive tract discomfort;

It has strong hygroscopicity and is easily deliquescent when exposed to air, so protection is required.

Protective measures:

Wear gloves and goggles during operation and use in a well-ventilated environment;

Avoid direct contact with skin and mucous membranes. If contact occurs, rinse with plenty of water in time.

Uses

Ionic liquid synthesis: As an intermediate for the preparation of functionalized ionic liquids, such as acetyl-functionalized imidazole ionic liquids, it is often used in organic synthesis, catalytic reactions or as a solvent.

Organic synthesis intermediate: Used in the synthesis of drugs, pesticides and fine chemicals, functional groups can be introduced through reactions such as acylation and alkylation.

Materials science: It has potential applications in polymer modification, electrolyte materials and other fields, and its ionic properties are used to improve material properties.

Storage conditions

Store in a sealed, dry, cool place, avoid moisture and high temperature. It is recommended to store in an inert gas environment (such as nitrogen) to prevent water absorption and deterioration.

Waste disposal

As chemical waste, it needs to be collected and handed over to a professional treatment agency for harmless disposal according to local regulations to avoid direct discharge into the environment.
