용도

Used as a protein denaturantUrea is a raw fabric for the manufacture of organic resins and is used as protein denaturant sealant and in agriculture, dyes, fuels, functional fluids, intermediates, paint additives and coating additives. Urea is used as a nitrogen-release fertilizer, on-corroding alternative to rock salt for road de-icing, browning agent in factory-produced pretzels, cloud seeding agent, a deep eutectic solvent and type of ionic liquid.

참고

Stable at room temperature. Incompatible with strong oxidizing agents.
