By Namon Hirun, Saowanit Saithong, Chaveng Pakawatchai and Vimon Tantishaiyakul


In the title compound, C7H6O5, the three hy­droxy groups on the ring are oriented in the same direction. There are two intra­molecular O—H⋯O hydrogen bonds in the ring. In the crystal, there are several inter­molecular O—H⋯O hydrogen bonds and a short contact of 2.7150 (18) Å between the O atoms of the para-OH groups of adjacent mol­ecules
