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.

Products Description of Bretazenil CAS#84379-13-5Brotacetin is a partial agonist of the GABAA receptor of the benzodiazepine class. It was first developed by Roche as an antianxiety drug. Studies have found that brotacetin can counteract the spasms caused by pentamethazine. At an antispasmodic dose (125-250 μg·kg-1), brotacetin combined with pyridostigmine (100 μg·kg-1, im) and aprofen (4 mg·kg-1, im) can prevent sarin and soman poisoning. Brotacetin has good antianxiety activity at a dose of 50-400 μg·kg-1. Compared with diazepam, it has little adverse reaction of myasthenia.
