Applications
Glyoxylic acid is a reagent for sulfinylmaleate synthesis. It is one of the chemicals used in the Hopkins Cole reaction. It is involved to check the presence of tryptophan in proteins. It is condensed with urea and 1,2-diaminobenzene to form heterocycles. It also undergoes Friedel-Crafts and cyclocondensation reactions to form bis(pentamethylphenyl) acetic acid and a beta-carboline respectively. It is employed in the synthesis of a sulfinylmaleate, which serves as an efficient dienophile for enantioselective Diels-Alder cycloadditions.

Solubility
Soluble in water, dimethyl sulfoxide and alcohol. Insoluble in diethyl ether and hydrocarbons.

Notes
Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible withbases, oxidizing agents and reducing agents.
