Reactions and Uses
Glyoxylic acid is about 10x stronger acid than acetic acid, with an acid dissociation constant of 4.7 × 10−4:
- (HO)2CHCOOH (HO)2CHCO2− + H+
With base, glyoxylic acid disproportionates:
- 2 OCHCOOH + H2O → HOCHCOOH + HOOC–COOH
Even though the aldehyde is a very minor component of its solutions, glyoxylic acid behaves as an aldehyde in its reactions. For example, it gives heterocycles upon condensation with urea and 1,2-diaminobenzene.

“We have all had the experience of finding that our reactions and perhaps even our deeds have denied beliefs we thought were ours.”
—James Baldwin (1924–1987)
“Prolonged, indiscriminate reviewing of books is a quite exceptionally thankless, irritating and exhausting job. It not only involves praising trash but constantly inventing reactions towards books about which one has no spontaneous feeling whatever.”
