ChEBI:Dikegulac is a member of dioxanes.

Dissolve -DAG in Et2O, filter, dry (MgSO4) it, filter it again and evaporate to give a yellow oil. Addition of one drop of H2O induces crystallisation to the monohydrate, which also forms rhombic crystals on recrystallisation from 95% EtOH/H2O at room temperature. [Flatt et al.
