The enhanced nucleophilicity of anisole vs. benzene reflects the influence of the methoxy group, which renders the ring more electron-rich. The methoxy group strongly affects the pi cloud of the ring as a mesomeric electron donor, more so than as an inductive electron withdrawing group despite the electronegativity of the oxygen.
It was approved for medical use in the European Union, [5] Switzerland, [citation needed] and the United States in 2007. [4] Methoxy polyethylene glycol-epoetin beta is made from erythropoietin by chemically linking the N-terminal amino group or the ε-amino group of any lysine present in the protein with methoxy polyethylene glycol butanoic acid.
In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula R−O−CH 3 . On a benzene ring , the Hammett equation classifies a methoxy substituent at the para position as an electron-donating group , but as an electron-withdrawing group if at the meta position.
They consist of a disubstituted benzene ring with methoxy group and one methyl group. All three are colorless flammable liquids which are soluble in organic solvents but poorly soluble in water. They are not of major commercial interest although they are precursors to the corresponding methoxybenzoic acids and methoxybenzaldehydes. [1]
5-MeO-DiPT tablets seized from Salem, Oregon 5-Methoxy- N , N -diisopropyltryptamine ( 5-MeO-DiPT , sometimes called foxy methoxy or simply foxy [ 2 ] ) is a psychedelic tryptamine and the methoxy derivative of diisopropyltryptamine (DiPT).
Propylene glycol methyl ether (PGME or 1-methoxy-2-propanol) is an organic solvent with a wide variety of industrial and commercial uses. [3] Similar to other glycol ethers, it is used as a carrier/solvent in printing/writing inks and paints/coatings. It also finds use as an industrial and commercial paint stripper.
Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
