Application

Imidazole can be used as a proton transfer agent in the synthesis of porous organic polymers because of its amphiprotic nature and fast proton transfer behavior.
Imidazole can be used as a catalyst in the following      
  • Silylation of alcohols, carboxylic acids, and amines in the presence of silyl chloride in DMF.      
  • To prepare acid chlorides from the corresponding carboxylic acids and phosgene.      
  • Imidazole-PPh3/I2 catalytic system used in the conversion of alcohols into iodides.      
  • Imidazole-PPh3/I2 is used in the diol deoxygenation reaction.      

Excellent for buffers in the range of pH 6.2-7.8
