Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
