Encyclopedia > Phenyl ring

In chemistry, the phenyl group or phenyl ring (often abbreviated as -Ph) is the functional group with the formula Chemistry (in Greek: χημεία) is the science of matter and its interactions with energy and itself (see physics, biology). ... In ecology functional groups are collections of organisms based on morphological, physiological, behavioral, biochemical, or environmental responses or on trophic criteria. ...

-C6H5

where the six carbon atoms are arranged in a cyclic manner. This hydrophobic and aromatic hydrocarbon unit can be found in many organic compounds. It can be thought of as being derived from benzene (C6H6). One of the simplest phenyl containing compounds is phenol. General Name, Symbol, Number Carbon, C, 6 Chemical series Nonmetals Group, Period, Block 14 (IVA), 2, p Density, Hardness 2267 kg/m3 0. ... General Name, Symbol, Number Hydrogen, H, 1 Chemical series nonmetals Group, Period, Block 1 (IA), 1, s Density, Hardness 0. ... In chemistry, hydrophobic or lipophilic species, or hydrophobes, tend to be electrically neutral and nonpolar, and thus prefer other neutral and nonpolar solvents or molecular environments. ... In chemistry, an aromatic molecule is one in which electrons are free to cycle around circular arrangements of atoms, which are alternately singly and doubly bonded to one another. ... In chemistry, a hydrocarbon is any chemical compounds that consists only of carbon (C) and hydrogen (H). ... An organic compound refers to any member of a large class of chemical compounds whose molecules contain carbon, with exception of carbides, carbonates and carbon oxides. ... Benzene, C6H6, PhH, or benzol is a colorless and flammable liquid with a pleasant, sweet smell. ... General Name, Symbol, Number Carbon, C, 6 Chemical series Nonmetals Group, Period, Block 14 (IVA), 2, p Density, Hardness 2267 kg/m3 0. ... General Name, Symbol, Number Hydrogen, H, 1 Chemical series nonmetals Group, Period, Block 1 (IA), 1, s Density, Hardness 0. ... Phenol, also known under the old name carbolic acid, is a colorless crystalline solid with a typical sweet tarry odor. ...


Presence of a phenyl group typically results in an 1H-NMR shift around 7.4ppm. Pacific Northwest National Laboratorys high magnetic field (800 MHz) NMR spectrometer being loaded with sample. ...


The phenylene group is formally a benzene di-radical. For example, poly(p-phenylene) is a polymer built up from phenylene repeating units. Radical is derived from the Latin word radix, which means root. In various fields of endeavor, it can mean: Sciences in chemistry, either an atom or molecule with at least one unpaired electron, or a group of atoms, charged or uncharged, that act as a single entity in reaction. ... Poly(p-phenylene) (PPP) is conducting polymer of the rigid-rod polymer host family. ... A polymer is a generic term used to describe a substantially long molecule. ...

Analogs of cytochalasin B as radiopharmaceuticals for nuclear imaging of trans-membrane glucose transport - Patent ... (0 words)
These analogs are identical to cytochalasin B except that the phenyl ring of cytochalasin B is either substituted with a radionuclide or replaced by a radionuclide or a group which includes a radionuclide.
For nonradioactive analogs of this invention in which R is a phenyl ring bearing an electrophilic activating group, the preferred position of the electrophilic activating group on the phenyl ting is the ortho-position.
For nonradioactive analogs in which R is a phenyl ring bearing a group replaceable by a radionuclide such as a radioactive halogen, the preferred position of replaceable group on the phenyl ring is the recta-position.
