Chemistry & industry
Pharmacology
Metabolism/Metabolites
Intake of some amount of nitrates and nitrites is a normal part of the nitrogen cycle in humans. In vivo conversion of nitrates to nitrites can occur in the gastrointestional tract under the right conditions, significantly enhancing nitrates' toxic potency. The major metabolic pathway for nitrate is conversion to nitrite, and then to ammonia. Nitrites, nitrates, and their metabolites are excreted in the urine. (L1137)

Applications
DescriptionCesium nitrate is a strong oxidizing material and may burst into flames when it is in contact with organic materials. Cesium nitrate is used as a colorant and oxidizer in the pyrotechnic industry, in petroleum cracking, in scintillation counters, and in x-ray phosphors. It is used as a promoter in heterogeneous catalysts.
UsesUsed in the synthesis of cesium nitratocuprate, Cs2[Cu(NO3)4], which crystallizes in a square-planar coordination around the Cu center.1
UsesA reagent used as a colorant and an oxidizer in pyrotechnic compositions
UsesCesium nitrate prisms are used in infrared spectroscopy, x-ray phosphors and scintillation counters. It is a precursor material for the synthesis of cesium nitratocuprate and cesium salts. Cesium nitrate doped on carbon-based ruthenium catalyst plays an important role in synthesis of ammonia.
