| (-)-O-ACETYL-L-MALIC ANHYDRIDE Usage And Synthesis |
Chemical Properties | White Crystalline Solid | Uses | (-)-O-Acetyl-L-Malic Anhydride can be used as intermediates for detergents via O-acetylmalic acid amides. Regioselective ring opening of malic acid anhydrides by carbon nucleophiles | Uses | (S)-(-)-2-Acetoxysuccinic anhydride is used as intermediates for detergents via O-acetylmalic acid amides. Regioselective ring opening of malic acid anhydrides by carbon nucleophiles. | Purification Methods | Recrystallise it from Ac2O and dry it in a vacuum over KOH, or by washing it with dry Et2O due to its deliquescent nature.
