Descripción

General description

4-Bromo-3-nitrotoluene (2-bromo-5-methylnitrobenzene, 1-bromo-4-methyl-2-nitrobenzene) is a halonitrobenzene. It has been synthesized from 4-methyl-2-nitroaniline and confirmed by ¹H NMR. The crystal structure of 1-bromo-4-methyl-2-nitrobenzene is found to be orthorhombic in the Pna2₁ space group. Its enthalpy of vaporization at boiling point has been determined.

Application

4-Bromo-3-nitrotoluene may be used as a starting material in the synthesis of 2-bromo-5-methylaniline and as a reagent in the synthesis of 2-nitro-4:4′-dimethyl-diphenyl by reacting with p-iodotoluene.
