OHCCOOH

OHCCOOH, also known as glyoxylic acid, is an organic compound with the chemical formula OHCCOOH. It is the simplest alpha-keto acid, featuring both an aldehyde and a carboxylic acid functional group. Glyoxylic acid exists as a solid at room temperature, typically appearing as white crystals. It is soluble in water and polar organic solvents. In aqueous solution, it readily hydrates to form the geminal diol, OHC(OH)2COOH, which is in equilibrium with the anhydrous form. This hydrate is the most common form encountered.

Industrially, glyoxylic acid is produced through various methods, including the oxidation of glyoxal or the electrochemical reduction of oxalic acid. It serves as a key intermediate in the synthesis of a wide range of chemicals. Its reactivity stems from the presence of both the aldehyde and carboxylic acid groups, allowing it to participate in numerous organic reactions such as aldol condensations, oxidations, and reductions.

Glyoxylic acid finds applications in the pharmaceutical industry as a precursor for certain drugs, in the production of fragrances and flavors, and as a component in some cosmetic formulations. It is also used in the synthesis of agrochemicals and dyes. Due to its reactivity, it is important to handle glyoxylic acid with appropriate safety precautions.
