This chemical is commonly used as an intermediate in the synthesis of dyes, antioxidants, pharmaceuticals, gasoline, gum inhibitors, poultry medicines, and as a corrosion inhibitor. Illustration of p-nitroaniline with two explicit hydrogen-bonded water molecules in the electrostatic embedding of the remaining solvent molecules. Table 4 . Calculated Electronic Transitions (in nm) Obtained for pNA Isolated and in SCW Using TD-DFT with CAM-B3LYP/aug-cc-pVDZ 2021-04-15 · Thus, p-Nitroaniline can be prepared by means of electrophilic aromatic substitution. To begin, nitric acid needs to be activated as it has little electrophilic power. Thus, concentrated sulfuric acid is added to protonate the nitric acid. pNA (p-nitroaniline) is the free form of pNA that can be used as a colorimetric marker and reference standard in colorimetric enzyme assays using pNA-based substrates.

*Please select more than one item to compare * p-Nitroaniline is a REACTIVE CHEMICAL and a DANGEROUS EXPLOSION HAZARD. IDENTIFICATION p-Nitroaniline is a bright yellow powder with a faint Ammonia-like odor. It is used as an intermediate in the manufacture of dyes, pharmaceuticals and pesticides. REASON FOR CITATION * p-Nitroaniline is on the Hazardous Substance List P-nitroaniline is a chromogenic molecule that is used as a dyestuff intermediate in industrial applications. In biochemical research, enzyme assays utilize modified aminoacyl or peptidyl p-nitroanilines as substrates. The enzyme catalyzes the release of free p-nitroaniline, which is the basis of the colorimetric determination of the enzyme physical, and toxicological properties have not been thoroughly investigated., p-Nitroaniline is readily absorbed by inhalation, ingestion, or skin absorption. It is a strong methemoglobin former.
