Additional Information for Identifying Methanol Molecule

• Structure Data File (SDF/MOL File) of methanol

  The structure data file (SDF/MOL File) of methanol is available for download in the SDF page of methanol, which provides the information on atoms, bonds, connectivity and coordinates of methanol. The methanol structure data file can be imported to most of the chemistry-related software, providing three-dimensional visualization and further analysis.

• Chemical structure of methanol

  The molecular structure image of methanol is available in chemical structure page of methanol, which provides the molecular geometry information, i.e., the spatial arrangement of atoms in methanol and the chemical bonds that hold the atoms together.

• Chemical formula of methanol

  The molecular formula of methanol is given in chemical formula page of methanol, which identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element.

• InChI (IUPAC International Chemical Identifier) information of methanol

  In addition to the molecular weight information, the structural information of methanol in a textual expression is available via InChi. The full standard InChI of methanol is given below:

  InChI=1S/CH4O/c1-2/h2H,1H3

  It can provide a way to encode the molecular information of methanol to facilitate the search for the compound information in databases and on the web.

  The condensed, 27 character standard InChIKey (hashed version of the full standard InChI) of methanol is:

  InChIKey=OKKJLVBELUTLKV-UHFFFAOYSA-N

  It may allow easier web searches for methanol. The InChIKey, however, needs to be linked to the full InChI as well in order to get back to the original structure of the methanol as the full standard InChI cannot be reconstructed from the InChIKey.
