There are six structural isomers, each with the molecular formula C 6 H 4 Br 2 O, ... 3,5-Dibromophenol, 1,3-Dibromo-5-hydroxybenzene Structural formula: CAS Number:
At room temperature, 2,4-dibromophenol is a solid with needle-like crystals. It melts at 38 °C (100.4 °F) and boils at 238.5 °C (461.3 °F). it has a molecular weight of 251.905 g/mol. It is soluble in water, ethanol, ether and benzene and slightly soluble in carbon tetrachloride. [1]
