Primary aromatic amineQuantitative structure–activity relationship (QSAR)Background:Aromatic amines, often used as intermediates for pharmaceutical synthesis, may be mutagenic and therefore pose a challenge as metabolites or impurities in drug development. However, predicting the mutagenicity of aromatic ...
(Scheme 2). Various side reactions can therefore take place, the nature of which depends upon the structure of the starting amine and the reaction conditions. For example,aromatic aminescan giveazoxy compoundsby reaction of nitroso compounds withhydroxylamineintermediates;aliphatic aminescan give nitroso...
Because of their alkaline character, the worst-case scenario of primary aromatic amine (PAA) migration from food contact materials is commonly simulated by the use of 3% (w/V) acetic acid. However, stability-related issues have already shown that this simulant might not be the best choice. To...

Primary aromatic amines (PAAs) present significant challenges in the prediction of mutagenicity using current standard quantitative structure activity relationship (QSAR) systems, which are knowledge-based and statistics-based, because of their low positive prediction values (PPVs). Previous studies have ...
Different amine molecules have been studied, including n-ButylAmine, di-n-ButylAmine, tri-n-ButylAmine and 1,4-ButaneDiAmine for primary, secondary, tertiary and multi-functional amines respectively. For the transport properties, we have calculated the viscosity coefficients as a function of ...
ortho-Palladation of a sterically crowded primary benzylamine, -phenylneopentylamine, was accomplished in a moderate yield of 50% in the reaction with the weakest of palladation agents (Li2PdCl4) under very mild conditions, due to a steric promotion of an aromatic C–H bond activation. The ...
