Tetrolic acid is a chemical compound that is primarily used in the synthesis of organic compounds. It is also known as 5-Carboxytetronic acid and Tetramethylolacetic acid. Tetrolic acid is a colorless, crystalline solid that is soluble in water, alcohol, and ether. It is a strong acid, and its acidic properties are due to the presence of the carboxylic acid group (-COOH) in its structure. Some of the synonyms for tetrolic acid include Tetramethylmalonic acid, Tetramethylglycollic acid, Tetramethylacetic acid, and 2,2-dimethylmalonic acid. Tetrolic acid is widely used in organic chemistry as a building block for the synthesis of various organic compounds.
