Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2. Consisting of a phenyl group ( −C 6 H 5 ) attached to an amino group ( −NH 2 ), aniline is the simplest aromatic amine .
N-Methylaniline (NMA) is an aniline derivative. It is an organic compound with the chemical formula C 6 H 5 NH(CH 3). The substance is a colorless viscous liquid, Samples turn brown when exposed to air. The chemical is insoluble in water.
Aniline is a benzenoid compound. The NH 2 group attached to the benzene ring means that there is a lone pair of electrons that can enter into conjugation with the benzene ring resulting in delocalization in the aniline. Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds.
β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine).
Acetanilide can be produced by reacting acetic anhydride with aniline: [7]. C 6 H 5 NH 2 + (CH 3 CO) 2 O → C 6 H 5 NHCOCH 3 + CH 3 COOH. The preparation used to be a traditional experiment in introductory organic chemistry lab classes, [8] but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially ...
o-Anisidine is a dangerous pollutant from the production of dyes. It is listed as RCRA hazardous waste , with the code K181. [ 6 ] The International Agency for Research on Cancer (IARC) has classified o -anisidine as a Group 2B, possible human carcinogen.
Health groups ‘advising a bit of moderation’ on aspartame consumption
The human anillin cDNA, located on Chr7, encodes a 1,125–amino acid protein with a predicted molecular mass of 124 kD and a pI of 8.1. The mouse anillin gene is located on Chromosome 9. [9] There are also numerous anillin-like protein homologues found outside of metazoans. In Schizosaccharomyces pombe (fission yeast), there are Mid1p and ...
