Dec 10, 2014Inclusion complex between N-phenyl-1-naphthylamine (NPN) and β-cyclodextrin (β-CD) was studied by FT-IR, 1 H and 2D NMR, XRD, FT-Raman, SEM and DSC techniques. The formation of 1:1 stoichiometric inclusion complex of NPN with β-CD was proposed based on the Nuclear magnetic resonance spectroscopy and Molecular docking study.

On the Mode of Action of N

N-phenyl-2-naphthylamine, a sediment contaminant previously identified as a major toxicant of site-specific importance was investigated for its mode of toxic action. From short-term bioassays with daphnids, fish eggs, bacteria, and algae it appears that this compound has specific phytotoxic properties at concentrations below 100 μg/L, which cannot be explained assuming an unspecific narcosis

N‐Phenyl‐2‐naphthylamine [MAK Value Documentation, 2011

N‐phenyl‐2‐naphthylamine was tested for some time as a component of the "naphthyl mix" (0.5% N‐phenyl‐2‐naphthylamine and 0.5% di‐2‐naphthyl‐1,4‐phenylenediamine). In American studies carried out between 1972 and 1976, this mix produced positive reactions in about 1% of the 900 to 3000 tested patients (Rudner 1977 ).
