3,3-DIMETHYLGLUTARIMIDE Usage And Synthesis

Chemical Properties

white to white-grey crystalline powder

Uses

3,3'-dimethylglutarimide were used as the barbital subsitutes. 3,3-di-methyl-glutarimide is involved formation of the heterodimer.

Purification Methods

Recrystallise the imide from hot H2O or EtOH [Arnett & Harrelson J Am Chem Soc 109 809 1987]. [Beilstein 21 H 391, 21 I 331, 21 II 309, 21 III/IV 4601, 21/9 V 592.]
