CAS 79-50-5

(±)-Pantolactone

Description:

(±)-Pantolactone, with the CAS number 79-50-5, is a cyclic lactone that is a derivative of pantothenic acid (vitamin B5). It exists as a racemic mixture of two enantiomers, which means it contains equal amounts of both the left- and right-handed forms of the molecule. This compound is typically a colorless to pale yellow liquid with a characteristic odor. It is soluble in water and organic solvents, making it versatile for various applications. (±)-Pantolactone is primarily used in the synthesis of pharmaceuticals and as an intermediate in the production of other chemical compounds. Its structure features a five-membered lactone ring, which contributes to its reactivity and potential for further chemical transformations. Additionally, it exhibits mild hygroscopic properties, allowing it to absorb moisture from the environment. Overall, (±)-Pantolactone is significant in organic chemistry and biochemistry due to its role in metabolic pathways and its utility in synthetic processes.
