2-Methyl-4-nitroaniline Usage And Synthesis
  • Description2-Methyl-4-nitroaniline was used in preparing in-plane aligned nanofibers by the electrospinning technique. It was the starting reagent in the synthesis of 3-chloro-5-methylphenyl isocyanate. It was used to deposit polycrystalline thin films on Ag, Cu and Si by conventional and partially ionized beam deposition.
