N-Phenyl-1-naphthylamine for synthesis. CAS 90-30-2, pH (H₂O) neutral. - Find MSDS or SDS, a COA, data sheets and more information.
N-Phenyl-1-naphthylamine (P 1 NA) and N-Phenyl-2-naphthylamine (P 2 NA) are both widely used as antioxidant and plant secondary metabolites. In this study, growth, esterase, photosynthetic activity and cell membrane integrity were used as biomarkers to compare biotoxicity of P 1 NA and P 2 NA on Microcystis aeruginosa.

Naphthalenamine, N-phenyl-. In wild-type MUP there is just enough room for the amine group of NPN to makes a water mediated hydrogen bond to Tyr120, whereas in Y120F MUP mutant, there is a slight shift and the amine group makes a direct hydrogen bond to Tyr120. Much is still unknown about the entropic and enthalpic effects of the MUP binding site.
So, what is phenylethylamine? A wonderful and powerful substance found in a number of foods, that helps to produce a powerful energy and mood-boost. To really feel the benefits, we recommend taking a PEA supplement, rather than gorging on chocolate or red wine.
PANA (N-Phenyl-alpha-naphthylamine) is a high-purity product widely used as an antioxidant in petroleum products, synthetic lubricants, rubber products, and as an organic intermediate. Petroleum Products: greases, turbine oils, heat transfer fluids, crankcase lubricants, transformer oils, hydraulic and transmission fluids, and metal working fluids.

N-Phenyl-2-naphthylamine (P2NA) was widely used as oxidation inhibitor, particularly in rubber manufacturing. Technical-grade P2NA was contaminated with carcinogenic 2-naphthylamine (2NA), and bladder cancer risk in exposed workers was attributed to this impurity.
N-phenyl-1-naphthylamine is mutagenic in rodents. It impaired the rate of development of frog embryos and increased the incidence of abnormal forms. No studies have been identified on possible reproductive effects or lactation of it in humans. Section 12: Ecological Information Ecological Data for ADDITIN RC 7132 440D/1760S

N-Phenyl-2-naphthylamine, initial concn of 100 ppm, exhibited a 0-29 % Theoretical BOD in a Japanese MITI test after 14 days of incubation at 25 deg C(2). N-phenyl-2-naphthylamine was shown to degrade to beta-naphthylamine in a screening study using activated sludge inoculum at 21 deg C(3). In this study, 44.2 and 9.3 %CO2 production was observed in 1 day at initial concns of 2 and 5 ppm, respectively(3).
Lubricant Antioxidants. TRiiSO distributes a wide range of antioxidants that allow formulators to produce high quality lubricants. Antioxidants protect lubricants from thermal degradation by scavenging free radicals, thereby preventing the oxidation of the lubricant. TRiiSO's portfolio of antioxidants include both phenolic and aminic varieties.
