2008). A similar synergism occurs in human bladder cancer secondary to cigarette smoke as seen in the synergism between the DNA reactivity from low levels of exposure to FANFT combined with cell proliferation p
Synthesis: Carbon with One Heteroatom Attached by a Single Bond 2.15.3.2Salts of Arylamines Aromatic aminesalts may be prepared simply by treating primary, secondary ortertiary amineswith the common mono- or polyproticmineral acidsor organic acids capable of protonating the amine (Equation (40))....
Why aromatic primary amines cannot be prepared by this method? (ii) Why are aromatic amines weaker bases than aliphatic amines? View Solution Account for any two of the following: (a) Amines are basic substances while amides are neural. (b) Aromatic amines are weaker bases than aliphatic ...

Heterocyclic aromatic amines (HAAs) form during the high-temperature cooking of meats, poultry, and fish. Some HAAs also arise during the combustion of tobacco. HAAs are multisite carcinogens in rodents, inducing cancer of the liver, gastrointestinal tract, pancreas, mammary, and prostate glands. ...
OCT1 (SLC22A1) transporter kinetics and regulation in primary human hepatocyte 3D spheroids ArticleOpen access27 July 2024 Introduction Exposure to aromatic amines (AA) is of concern in pharmaceutical development, as well as in occupational and wider environmental contexts, due to their potential toxi...

As it is well known, primary aliphatic aldehydes, in general, give polymeric materials with amines, due to the ease with which the imines initially formed, undergo subsequent aldol condensations [32]. On the other side, the reactions of ketones (both aromatic and aliphatic ones) were ...
It is preferred that the curing agent used should be an amine, with the weight ratio epoxy compound/amine in the mixture to be applied to the yarn being in the range of 50:1 to 1:1. A preferred amine is piperazine. Optionally, use may be made of a mixture of amines, such as a ...
