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