The yellow crystalline powder of p-nitrobenzoic acid is odorless and can sublimate. Slightly soluble in water, soluble in organic solvents such as ethanol. Combustible in case of open fire and high heat. Thermal decomposition. Intermediates for organic synthesis of pharmaceuticals, dyes, veterinary drugs, photosensitive materials, etc. It can be obtained by oxidation of p-nitrotoluene.

Chemical property: flammable in case of open fire and high heat. Toxic nitrogen oxide flue gas is released by thermal decomposition.
