4-Chloroaniline is used in the industrial production of pesticides, drugs, and dyestuffs. It is a precursor to the widely used antimicrobial and bacteriocide chlorhexidine and is used in the manufacture of pesticides, including pyraclostrobin , anilofos , monolinuron , and chlorphthalim .
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 ...
Fluoroaniline may refer to three compounds with the formula FC 6 H 4 NH 2: 2-Fluoroaniline; 3-Fluoroaniline; 4-Fluoroaniline This page was last edited on 9 ...
A more convenient alternative to SF 4 is the diethylaminosulfur trifluoride, which is a liquid whereas SF 4 is a corrosive gas: [19] [20] C 6 H 5 CHO + R 2 NSF 3 → C 6 H 5 CHF 2 + "R 2 NSOF" Apart from DAST, a wide variety of similar reagents exist, including, but not limited to, 2-pyridinesulfonyl fluoride (PyFluor) and N -tosyl-4 ...
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.
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
An easy example is that of CFC-12, which gives: 90+12=102 -> 1 carbon, 0 hydrogens, 2 fluorine atoms, and hence 2 chlorine atoms resulting in CCl 2 F 2. The main advantage of this method of deducing the molecular composition in comparison with the method described in the paragraph above is that it gives the number of carbon atoms of the molecule.
Tetrachloroaluminate [AlCl 4] − is an anion formed from aluminium and chlorine.The anion has a tetrahedral shape and is isoelectronic with silicon tetrachloride.Some tetrachloroaluminates are soluble in organic solvents, creating an ionic non-aqueous solution, making them suitable as component of electrolytes for batteries.
