Tetrachloro-1,2-difluoroethane is a chlorofluorocarbon known as Freon 112, CFC-112 or R-112. It has a symmetrical structure CCl 2 FCCl 2 F and so can be called symmetrical tetrachlorodifluoroethane. "Symmetrical" may also be abbreviated to "s-" or "sym-". In contrast an asymmetrical isomer has formula CCl 3 CClF 2.
EDTMP is normally delivered as its sodium salt, which exhibits good solubility in water. Used in Water treatment as an antiscaling and anti corrosion agent, the corrosion inhibition of EDTMP is 3–5 times better than that of inorganic polyphosphate.
2,3,7,8-Tetrachlorodibenzofuran (TCDF) is a polychlorinated dibenzofuran with a chemical formula of C 12 H 4 Cl 4 O. TCDF is part of the chlorinated benzofuran (CDF) family that contains between 1 and 8 chlorine atoms attached to the parent dibenzofuran ring system. The CDF family includes 135 compounds, of which only a few have been studied.
General chemical structure of PCDFs, where 1 ≤ n+m ≤ 8 Structures of the ten 2,3,7,8-substituted PCDF congeners that are toxicologically of most relevance Polychlorinated dibenzofurans ( PCDFs ) are a family of organic compounds with one or several of the hydrogens in the dibenzofuran structure replaced by chlorines.
The tetratricopeptide repeat (TPR) is a structural motif.It consists of a degenerate 34 amino acid tandem repeat identified in a wide variety of proteins.It is found in tandem arrays of 3–16 motifs, [1] which form scaffolds to mediate protein–protein interactions and often the assembly of multiprotein complexes.
