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
Sulfonic acid generated readily from benzene. Sulfonic acid A sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O)−OH, where R is an organic alkyl or aryl group and the S(=O)(OH) group a sulfonyl hydroxide. A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound (with the organic substituent replaced by hydrogen) is the parent sulfonic acid, HS(=O)(OH), a tautomer of sulfurous acid, S(=O)(OH). Salts or esters of sulfonic acids are called sulfonates. A sulfonic acid is produced by the
