The propionate or propanoate ion is C2H5COO (propionic acid minus one hydrogen ion).

A propionic or propanoic compound is a small salt or ester of propionic acid. In these compounds, propionate is often written in shorthand, as CH3CH2CO2 or simply EtCO2.

Propionates should not be confused with propenoates (commonly known as acrylates), the ions/salts/esters of propenoic acid (also known as 2-propenoic acid or acrylic acid).
