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 providing the information about the atoms, bonds, connectivity and coordinates of methanol, which is not completely available in the chemical formula representation. The methanol structure data file can be imported to most of the cheminformatics software for further analysis and visualization.

• Chemical structure of methanol

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

• Molecular weight of methanol

  The molecular weight of methanol is available in molecular weight page of methanol, which is calculated as the sum of the atomic weights of each constituent element multiplied by the number of atoms of that element specified in the chemical formula of methanol.

• InChI (IUPAC International Chemical Identifier) information of methanol

  The molecular chemical formulas lack structural information. An alternative textual expression including the structural information is InChI. The full standard InChI of methanol is:

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

  It can provide a standard 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

  The InChIKey may allow easier web searches for methanol, but it needs to be linked to the full InChI to get back to the original structure of the methanol since the full standard InChI cannot be reconstructed from the InChIKey.
