DMI ref. omg098 Image title: Urea crystal melt. | 46.48
Urea (carbamide, CAS# 57-13-6) is a metabolic byproduct of the digestion of nitrogen-containing compounds (e.g. protein, meat). It is readily synthesised and it is used in the manufacture of plastics such as urea-formaldehyde resin. Its nitrogen content makes it useful as a fertilizer.
