4-Nitroaniline-2,3,5,6-D4 is a labelled analogue of 4-Nitroaniline (N490770). 4-Nitroaniline is used in the synthesis of photorefractive polymers, as novel chromophores in analytical study. As well, due to the absorption spectrum associated with 4-Nitroaniline, it is used to determine catechol derivatives in syntheses.
