(2,3-Dihydro-1,4-benzodioxin-2-yl)methanol

In the title compound, C9H10O3, the heterocyclic ring has a half-chair conformation. The –CH2OH substituent is attached equatorially with respect to the heterocyclic ring. In the crystal structure, the mol­ecules are linked by O—H⋯O hydrogen bonds, with the hydroxyl O atom functioning both as donor and acceptor. This results in the formation of C(2) helical chains running along the fourfold screw axes.
