1,2,4,5-Tetrabromobenzene

<p>1,2,4,5-Tetrabromobenzene is a brominated organic compound that forms a palladium complex. It has been studied by chemical ionization with an atmospheric pressure photoionization detector (APPI) and molecular modeling. The debromination reaction of 1,2,4,5-tetrabromobenzene was observed to take place in the liquid phase at room temperature. The detection limit for this reaction was found to be between 0.1 and 5 ppm. The most common form of 1,2,4,5-tetrabromobenzene is the monoclinic polymorph; however it can also exist as a trigonal system or as a hexagonal system when heated above its phase transition temperature. This compound is soluble in water and mercury chloride solutions but insoluble in ethers or chloroform.</p>
