Uses Pharmacaeutical Urea and malonic acid react to form barbituric acid. This was discovered by Adolf Bayer in But the barbiturates were not exploited as hypnotics until the early 's. Urea is also used in the production of various acylureas and urethanes for use as sedatives and hypnotics.

Resins Melamine is formed by the dehydration of urea. Almost years elapsed between Liebig's discovery in and a commercial process being developed. Melamine is primarily used in the production of melamine-formaldehyde resins which have much greater hardness and stain resistance than urea-formaldehyde resins.

Both melamine-formaldehyde and urea-formaldehyde have very varied uses including adhesives, laminates, moulding compounds, coatings and textile finishes.
