Dab tsi yog(S)-3-Hydroxy-gamma-butyrolactoneCAS7331-52-4

(s) 3-hydroxy - γ - butyrolactone yog cov kua tsis muaj xim uas yog soluble hauv dej, cawv, thiab lwm yam organic solvents, tab sis insoluble hauv roj av ethers. Nws yog ib qho tseem ceeb heev organic synthesis intermediate thiab ib qho tseem ceeb heev chiral qhov chaw (Chiral Pool). Nws yog tsuas yog siv los ua ib qho tseem ceeb nruab nrab ntawm kev tswj hwm (R) - γ - hydroxy - β - Q hydroxybutyric acid [(R) - GABOB], uas yog siv los kho hyperlipidemia; (s) Oxiracetam yog ib qho kev txhawb nqa ntawm lub hlwb metabolism thiab nws cov synthesis; (s) -3-hydroxytetrahydrofuran tuaj yeem tau los ntawm kev txo qis, uas yog ib qho tseem ceeb ntawm cov tshuaj AIDS.
