Urea CAS#57-13-6The urea molecule is planar in the crystal structure, but the geometry around the nitrogens is pyramidal in the gas-phase minimum-energy structure. In solid urea, the oxygen center is engaged in two N-H-O hydrogen bonds. The resulting dense and energetically favourable hydrogen-bond network is probably established at the cost of efficient molecular packing: The structure is quite open, the ribbons forming tunnels with square cross-section.

Products Description of Urea CAS#57-13-6When the temperature is below 20℃ and the relative humidity is below 70%, urea not only does not absorb moisture, but also evaporates water to reduce its water content; when the temperature exceeds 20℃ and the relative humidity is higher than 80%, it begins to absorb moisture, and in severe cases, it becomes a paste. When the air turns dry again, it will re-agglomerate, and its degree is second only to ammonium nitrate.
