Glyoxylic acid rats of 2500 mg/kg. Glyoxylic acid Glyoxylic acid or oxoacetic acid is an organic compound. Together with acetic acid, glycolic acid, and oxalic acid, glyoxylic acid is one of the C carboxylic acids. It is a colourless solid that occurs naturally and is useful industrially. Glyoxylic acid is usually described with the chemical formula OCHCOH, i.e. containing an aldehyde functional group (see image in upper right). The aldehyde in fact is not observed in solution or as a solid. As seen for many other aldehydes, it exists most commonly as the hydrate. Thus, the formula for glyoxylic acid is really
Nitroacetic acid Nitroacetic acid Nitroacetic acid is the chemical compound with the formula (NO)CHCOH. This substituted carboxylic acid is used as a potential precursor to nitromethane, commonly used as a fuel in drag racing and as an organic reagent in chemical synthesis. Nitroacetic acid can be synthesized by adding cold chloroacetic acid into a cold, slightly alkaline aqueous solution, followed by mixing with aqueous sodium nitrite solution. It is important during this procedure not to make the solution too alkaline and to keep it cold to prevent the formation of sodium glycolate. Nitroacetic acid can be used in the production of nitromethane
