- What is N-phenyl-2-naphthylamine?
- Computed by PubChem 2.2 (PubChem release 2021.10.14) N-phenyl-2-naphthylamine is a light gray to gray powder. Solutions show blue fluorescence. (NTP, 1992) National Toxicology Program, Institute of Environmental Health Sciences, National Institutes of Health (NTP). 1992. National Toxicology Program Chemical Repository Database.
- How does N-phenyl-2-naphthylamine affect the environment?
- In occupational settings, workers may be exposed to N-phenyl-2-naphthylamine through inhalation and through eye and skin contact. (SRC) N-Phenyl-2-naphthylamine is used as an antioxidant, lubricant, and inhibitor (1) and, therefore, it may be released to the environment during its production and use (SRC).
- Is N-phenyl-beta-naphthylamine dangerous?
- A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. The substance may be irritating to the skin and eyes. Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans. Excerpt from NIOSH Pocket Guide for N-Phenyl-beta-naphthylamine:
- Does N-phenyl-2-naphthylamine hydrolyze in water?
- Aromatic amines are generally resistant to aqueous environmental hydrolysis (2); therefore, N-phenyl-2-naphthylamine is not expected to hydrolyze in water (SRC).
- Where is N-phenyl-2-naphthylamine released?
- N-Phenyl-2-naphthylamine is probably released to the environment in waste streams from its production and use. In the atmosphere, it should exist in the vapor and particulate phases. Vapor phase N-phenyl-2-naphthylamine is expected to degrade rapidly (estimated half-life of 55 minutes) by reaction with photochemically produced hydroxyl radicals.
- Is N-phenyl-2-naphthylamine immobile in soil?
- Based on an experimental log octanol - water partition coefficient of 4.38 (2) and a recommended regression-derived equation (1), the Koc value for N-phenyl-2-naphthylamine can be estimated to be 12,500 (SRC). According to a suggested classification scheme (3), this Koc value indicates that N-phenyl-2-naphthylamine will be immobile in soil.
