4-Fluoroephedrine, also known as 4-fluoro-β-hydroxy-N-methylamphetamine, is a substituted phenethylamine, amphetamine, and β-hydroxyamphetamine derivative. [6] [1] It is the 4-fluoro analogue of ephedrine. [6] [1] The synthesis of 4-fluoroephedrine has been described. [7] It can serve as a precursor in the synthesis of 4-fluoromethamphetamine ...
4-Fluoroaniline can be prepared by the hydrogenation of 4-nitrofluorobenzene. [2] It is a common building block in medicinal chemistry and related fields. [3] For example, it is a precursor to the fungicide fluoroimide or the fentanyl analogue parafluorofentanyl. It has also been evaluated for the production of ligands for homogeneous catalysis ...
It is one of three isomeric fluoronitrobenzenes. [2] A yellow oil, it is prepared from 4-nitrochlorobenzene using the Halex process: O 2 NC 6 H 4 Cl + KF → O 2 NC 6 H 4 F + KCl. 4-Fluoronitrobenzene can be hydrogenated to give 4-fluoroaniline, [3] which is a precursor to the fungicide fluoroimide and parafluorofentanyl.
The term nitroaniline in chemistry refers to a derivative of aniline (C 6 H 5 NH 2) containing a nitro group (—NO 2) There are three simple nitroanilines of formula C 6 H 4 (NH 2)(NO 2) which differ only in the position of the nitro group: 2-Nitroaniline; 3-Nitroaniline; 4-Nitroaniline
Ephedrine Sulphate (1932), Ephedrine Compound (1932), and Swan-Myers Ephedrine Inhalant No. 66 (circa 1940).Ephedrine is a non-catecholamine sympathomimetic with cardiovascular effects similar to those of adrenaline/epinephrine: increased blood pressure, heart rate, and contractility.
2-Nitroaniline is prepared commercially by the reaction of 2-nitrochlorobenzene with ammonia: [2] ClC 6 H 4 NO 2 + 2 NH 3 → H 2 NC 6 H 4 NO 2 + NH 4 Cl. Many other methods exist for the synthesis of this compound. Direct nitration of aniline is inefficient since anilinium is produced instead. Nitration of acetanilide gives only traces of 2 ...
Guinness Draught (4.2% ABV) Guinness, an Irish Dry Stout, is a fantastic example to disprove a common misconception, that dark beers are higher in alcohol. Malt has nothing to do with alcohol content.
4-Nitroaniline, p-nitroaniline or 1-amino-4-nitrobenzene is an organic compound with the formula C 6 H 6 N 2 O 2. A yellow solid, it is one of three isomers of nitroaniline. It is an intermediate in the production of dyes, antioxidants, pharmaceuticals, gasoline, gum inhibitors, poultry medicines, and as a corrosion inhibitor. [3]
