Glyoxylic acid monohydrate Usage And Synthesis

Chemical Properties

white to light yellow crystalline powder or chunks

Uses

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.

Uses

Occurs in unripe fruit and in young green leaves; has also been found in very young sugar beets.
