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
Mandelic acid urinary tract infections. It has also been used as an oral antibiotic, and as a component of chemical face peels, along with other alpha-hydroxy acids (AHAs). Mandelic acid Mandelic acid is an aromatic alpha hydroxy acid with the molecular formula CHCH(OH)COH. It is a white crystalline solid that is soluble in water and polar organic solvents. It is a useful precursor to various drugs. The molecule is chiral. The racemic mixture is known as "paramandelic acid". Mandelic acid was discovered in 1831 by the German pharmacist Ferdinand Ludwig Winckler (1801–1868) while heating amygdalin, an extract of bitter almonds, with diluted
