The dibydrochloride salt is used as a photographic developer. It also is employed as an intermediate in the manufacture of fur dyes, in hair dyeing, as a reagent in testing for ammonia and formaldehyde, and as an oxygen scavenger in water to prevent boiler corrosion (173). 

Frequent inflammation of the pharynx and larynx has heen reported in exposed workers. Very small quantities of the dust have caused asthmatic attacks in workers after periods of exposure ranging from 3 months to 10 years. Sensitization dermatitis has heen reported from its use in the fur dyeing industry. In this process, oxidation products of p-phenylenedi-amine are generated that are also strong skin sensitizers. Many instances of inflammation and damage of periocular and ocular tissue have been reported from contact with hair dyes containing p-phenylenediamine, presumably in sensitized individuals. ...
