-oate

From Wikipedia, the free encyclopedia

The suffix -oate is the IUPAC nomenclature used in organic chemistry to form names of compounds formed from carboxylic acids. They are of two types:

  • Formed by replacing the hydrogen atom in the –COOH by some other radical, for example methyl benzoate C6H5–CO–OCH3
  • Formed by removing the nucleus (proton) of the hydrogen atom in the –COOH, producing an anion: then add a cation, for example sodium benzoate C6H5–CO–O− Na+

The suffix is derived from "-oic acid".
