• InChI (IUPAC International Chemical Identifier) information of acetic acid

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

  InChI=1S/C2H4O2/c1-2(3)4/h1H3,(H,3,4)

  It can provide a way to encode the molecular information of acetic acid 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 acetic acid is:

  InChIKey=QTBSBXVTEAMEQO-UHFFFAOYSA-N

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