What is (S)-3-Hydroxy-gamma-butyrolactone CAS 7331-52-4？

(s) 3-hydroxy - γ - butyrolactone is a colorless liquid that is soluble in water, alcohols, and other organic solvents, but insoluble in petroleum ethers. It is a very important organic synthesis intermediate and a very important chiral source (Chiral Pool). It is mainly used as a key intermediate for regulating (R) - γ - hydroxy - β - Q hydroxybutyric acid [(R) - GABOB], which is used to treat hyperlipidemia; (s) Oxiracetam is a promoter of brain metabolism and its synthesis; (s) -3-hydroxytetrahydrofuran can be obtained by reducing it, which is an important intermediate of AIDS drugs
