Chemical Formula Description

The Angelaldehyde molecule contains a total of 14 atom(s). There are 8 Hydrogen atom(s), 5 Carbon atom(s) and 1 Oxygen atom(s). A chemical formula of Angelaldehyde can therefore be written as:


The chemical formula of Angelaldehyde shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.

The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions. The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula.

Additional Information for Identifying Angelaldehyde Molecule

  • InChI (IUPAC International Chemical Identifier) information of Angelaldehyde

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


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


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