Descrição geral

4,7,13,16,21,24-Hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane(cryptand 222, Kryptofix 222) is an organic compound with formula C18H36N2O6. This compound has a cage-like three-dimensional structure that donates N2O6. The ligand has shown a wide range of uses in magnetic resonance imaging, organic synthesis, crystallography, electrochemistry, and chromatography. In solution, it is a well-known sequestering agent for metal ions.

Aplicação

4,7,13,16,21,24-Hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane is used as:

  • A electrolyte additive in isotachophoresis[separation method that is particularly suited to the analysis of small ions]for the analysis of alkali metal cations.
  • A complexing agent in the preparation of K+-imprinted nanoparticles using methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the crosslinker and 2,2′-azobisisobutyronitrile as the radical initiator.
  • A structure directing agent (SDA) in the preparation of LTA-type AlPO4 crystals.

Embalagem

Bottomless glass bottle. Contents are inside inserted fused cone.
Cryptand used with potassium mirror to reduce a hindered distannene to a crystalline radical anion.

Stable Isotopes in PET (Positron Emission Tomography)

Labeled isotopes used as target materials in imaging have provided insights into the various mechanisms of human physiology and have lead to treatments for diseases. Water-18O is used for the production of 18F radionuclides, such as 18FDG (Fluoro-deoxyglucose). 18FDG used in PET and with other imaging technologies, such as CT/SPECT, has led to the diagnosis and treatment of a wide range of diseases, including lung, liver, and brain tumors, epilepsy, and Alzheimer’s.
