What is it used for?

Applications & Reactions

How Urea (CO(NH₂)₂) is used across industries, with the key chemistry explained simply.

Agriculture

Nitrogen Fertiliser

Hydrolysed in soil by the enzyme urease to release ammonium carbonate, providing readily available nitrogen to crops. The most concentrated solid nitrogen fertiliser (46% N).

OCOCO₂

Urease hydrolysis in soil

CO(NH₂)₂ + H₂O → 2NH₃ + CO₂

Transport & Emissions

AdBlue / Diesel Exhaust Fluid (DEF)

32.5% aqueous urea solution injected into diesel exhaust to reduce NOₓ emissions via Selective Catalytic Reduction (SCR). Required by Euro IV–VI and EPA Tier 4 vehicles.

CONNHHHHCO(NH₂)₂
OHHH₂O

SCR NOₓ reduction

CO(NH₂)₂ → NH₃ → reduces NOₓ to N₂ + H₂O

Chemical Industry

Urea-Formaldehyde Resins

Reacts with formaldehyde under acid catalysis to produce thermosetting resins widely used as adhesives in plywood, chipboard, MDF, and furniture manufacturing.

Agriculture

Animal Feed Supplement

Non-protein nitrogen source added to ruminant feed. Rumen bacteria convert urea to ammonia and then to amino acids, reducing dependence on costly protein meal.
