Application

Reagent for the conversion of alcohols to chlorides and for the immobilization of microorganisms and enzymes.
Cyanuric chloride can be used as a reagent:   
  • In the preparation of acyl azides from carboxylic acids and sodium azide.       
  • For the conversion of carboxylic acids, N-Boc, N-Cbz, and N-Fmoc amino acids into corresponding alcohols.      
  • For the conversion of alcohols into the corresponding carbonyl compounds by alternative Swern oxidation reaction.


It can also be employed as a catalyst in the Beckmann rearrangement of ketoximes into amides in the presence of ZnCl2.
