p-Phenylenediamine is used as a precursor to aramid plastics, Kevlar fibers and to urethane polymers. It serves as a developing agent in photography, antioxidants in rubber products and as a vulcanization accelerator. It is used as a henna surrogate for temporary tattoos and as a histological stain for lipids such as myelin. It is an anti-fade reagent used in fluorescence microscopy to retard photobleaching of fluorescein and other fluorescent dyes. Furthermore, it is also an ingredient in hair dyes.
