What is 4-Chloro-2-nitrotoluene?
Chemical properties
clear brown liquid after melting
The Uses of 4-Chloro-2-nitrotoluene
4-Chloro-2-nitrotoluene can be used in the synthesis of indigo dye.
The Uses of 4-Chloro-2-nitrotoluene
4-Chloro-1-methyl-2-nitrobenzene is used in the synthesis of NMDA-glycine antagonists. Also it is used in the preparation of COX-2 inhibitor.
Production Methods
4-Chlorotoluene is nitrated with mixed acid (39/59/2) at 25 ℃ to give a mixture of 4-Chloro-2-nitrotoluene (65 %) and 4-Chloro-3-nitrotoluene (35 %) isomers. The major component is separated as the lower boiling fraction on vacuum distillation. 4-Chloro-3-nitrotoluene [89-60-1] can be obtained, if required, from the residue by distillation and sweating.
Biochem/physiol Actions
4-Chloro-2-nitrotoluene is the starting reagent for synthesis of tricyclic indole-2-carboxylic acids, a potential NMDA-glycine antagonists.
