p-Phenylenediamine, also known as Ursol D, is one of the simplest aromatic diamines and a widely used intermediate. It is utilized in the production of azo dyes, polymer polymers, fur dyes, rubber antioxidants, photographic developers, and serves as a sensitive reagent for testing iron and copper. p-Phenylenediamine is a crucial dye intermediate, primarily employed in aramid fibers, azo dyes, sulfur dyes, acid dyes, and more.
