n-Propyl gallate (PG) is a charge-control agent used for toners in electrophotography, and shows pseudo-polymorphism. In the asymmetric unit of the title compound, 3 C10H12O5·0.5CHCl3, there are three PG mol­ecules and a half-mol­ecule of chloroform, the solvent molecule being disordered over an inversion centre. There are intra- and intermolecular O—H...O hydrogen bonds, forming a two-dimensional hydrogen-bond network in the (421) plane.

n-Propyl gallate (PG) is a charge-control agent used for toners in electrophotography, and shows pseudo-polymorphism. The title compound, 3C10H12O5·0.5CH2Cl2, is isostructural with the corresponding chloro­form solvate. The asymmetric unit is composed of three PG mol­ecules and a half-mol­ecule of dichloromethane, the solvent being disordered over an inversion centre. There are intra- and inter­molecular O—H...O hydrogen bonds, forming a two-dimensional hydrogen-bond network in the (421) plane.
