Deep Data Application Examples

Our Deep Data encompasses property data, spectral data, quantum chemical data, and molecular descriptor data for a wide range of chemical compounds. It features more than 2,100 high-quality datasets per single chemical compound, totaling over 8 billion datasets for 4.1+ million chemical compounds. Below are some application examples that may interest you:

Additional Information for Identifying Oxygen Molecule

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

  The structure data file (SDF/MOL File) of Oxygen is available for download in the SDF page of Oxygen providing the information about the atoms, bonds, connectivity and coordinates of Oxygen, which is not completely available in the chemical formula representation. The Oxygen structure data file can be imported to most of the cheminformatics software for further analysis and visualization.

• Chemical structure of Oxygen

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

• Molecular weight of Oxygen

  The molecular weight of Oxygen is available in molecular weight page of Oxygen, 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 Oxygen.

• InChI (IUPAC International Chemical Identifier) information of Oxygen

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

  InChI=1S/O2/c1-2

  It can provide a standard way to encode the molecular information of Oxygen 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 Oxygen is:

  InChIKey=MYMOFIZGZYHOMD-UHFFFAOYSA-N

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