Following this, crude tyramine was procured by heating tyrosine in the presence of the catalyst diphenylamine.

Nitrated analogs of diphenylamine formed in the process of stabilizing decomposing powder are sometimes used as stabilizers themselves.
13.
Diphenylamine has low acute and short-term toxicity to birds, but is very toxic to aquatic organisms.
14.
While N-methyl-p-nitroaniline ( MNA also used in IMX-101 ), and diphenylamine ( DPA ) are more commonly employed.
15.
McCarty's arrival at Rockefeller University was also marked by another milestone, namely, the development of a diphenylamine reagent assay to positively correlate DNA with biological activity.
16.
The'European Diphenylamine Task Force'resubmitted an application to the EC with more data, and an additional report was received by the EFSA on 3 December 2010.
17.
The compound was originally prepared by Bernthsen in 1883 via the reaction of diphenylamine with sulfur, but more recent syntheses rely on the cyclization of 2-substituted diphenyl sulfides.

Diphenylamine derivatives, such as ring-alkylated derivatives of diphenylamine are used as anti-ozonants in the manufacture of rubber products, reflecting the antioxidant nature of aniline derivatives.

20.
Suspected samples can be tested for phosgene using filter paper ( treated with 5 % diphenylamine, 5 % dimethylaminobenzaldehyde in ethanol, and then dried ), which turns yellow in phosgene vapor.
