General description

The product is a 70% solution of glycolic acid nitrile in water. Glycolic acid nitrile, also known as hydroxyacetonitrile is the simplest cyanohydrin. The microwave spectra of hydroxyacetonitrile have been recorded in gas-phase and its rotational constants have been calculated. Ice containing formaldehyde and hydrogen cyanide react under astrophysical-like conditions to form hydroxyacetonitrile.
