Description of key information

It can be concluded that hydrolysis is no relevant pathway or a pathway of minor importance for N-phenyl-1-naphthylamine in the environment. Photodegradation of N-phenyl-1-naphtylamine in aqueous solutions by sunlight is rapid and proceeds with a half-life of 5 to 8 min. One primary photoproduct was identified which is relatively photostable, probably the aniline adduct of 1,3-naphthoquinone.
