    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.

    The format was originally developed and published by Molecular Design Limited (MDL). MOL is another file format from MDL. It is documented in Chapter 4 of CTfile Formats. [6] PubChem also has XML and ASN1 file formats, which are export options from the PubChem online database. They are both text based (ASN1 is most often a binary format).

    It can also be prepared by the method originally used by acid's discoverer Alexander William Williamson in 1854, [4] namely chlorination of sulfuric acid, written here for pedagogical purposes as HSO 3 (OH) vs. the usual format H 2 SO 4: PCl 5 + HSO 3 (OH) → HSO 3 Cl + POCl 3 + HCl. The latter method is more suited for laboratory-scale ...
