individually or in a mixture. Examples of polyamines for corresponding amines are alkylenediamines and oligomers thereof, such as ethylenediamine, propylenediamine and butylenediamine, diethylenetriamine and tetramines, and higher homologs of these amines, and furthermore aminoalcohols, such as ...

unsymmetrical azoalkane (R--N═N--R'), are prepared by reacting 4 equivalents of a mixture of two or more primary alkyl, cycloalkyl or aralkylamines with 1 equivalent of sulfuryl chloride in an inert solvent and oxidizing the resulting mixture of sulfamide products with basic bleach. ...
Suitable bases are both organic and inorganic bases, e.g. tertiary amines such as trialkylamines (trimethylamine, triethylamine, tripropylamine, diisopropylethylamine etc.), pyridine and pyridine bases (4-dimethylaminopyridine, 4-pyrrolidylaminopyridine etc.), N-methylpyrrolidone etc., as well as ox...
All three amines inhibited the 5-HT3A receptor, the IC50 for propylamine in the equilibrium application was 5.6 mM; the more lipophilic amines pentylamine and nonylamine inhibit even more potently (data not shown) as expected [3]. If the alkylamines showed activation too weak to be ...

Beside the regulated AAs, the list contains 6 arylamines, 2 azo dyes, and 6 dyes/colorants with carcinogenic potential, which may cleave to carcinogenic aromatic amines or are carcinogenic, mutagenic or toxic to reproduction. None of the AAs proposed for restriction was found in our database. ...
