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 .
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.
Carbonic acid equilibria are important for acid–base homeostasis in the human body. An amino acid is also amphoteric with the added complication that the neutral molecule is subject to an internal acid–base equilibrium in which the basic amino group attracts and binds the proton from the acidic carboxyl group, forming a zwitterion .
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.
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.
One representative example is the New Zealand provisions enacted in 1988 in response to the first wave of fentanyl derivatives. This bans a set of structures as follows; "Fentanyl analogues, in which the N-[1-(2-phenethyl)-4-piperidyl]aniline nucleus has additional radicals, either alone or in combination, attached as follows:
The “One Chip Challenge” is a challenge created by the brand Paqui, which encourages consumers to eat one of the company's very spicy tortilla chips. The chip is dusted with Carolina Reaper ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
