Application

Chloramine T trihydrate may be used as an oxidizing agent in the synthesis of 8-chloro-[1,2,4]triazolo[4,3-a]pyrazine derivatives and novel isoxazolines.
It may also be used in the synthesis of the following compounds:
  • Nitrile imines by the oxidative dehydrogenation of N-(nitrobenzyl)-imidazole aldehyde hydrazine.
  • Mono-N-tosylated-1,2-diamines.
  • 3,5-Disubstituted isoxazoles.
  • Fused 3,6-disubstituted triazolothiadiazoles by the oxidative cyclization of N-heteroaryl-substituted hydrazones.
Nitrene source for aziridinations and aminohydroxylations.

General description

Chloramine T (CAT) trihydrate is a commonly used reagent for organic synthesis especially in heterocyclic chemistry. CAT is an active chlorine compound that shows antimicrobial activity.

Packaging

Capable of oxidative cyclization to produce various heterocycles.
