Descrizione generale
Tetrabromohydroquinone (TBHQ), also known as 2,3,5,6-tetrabromohydroquinone, can be synthesized by reacting bromanil with phenyl phosphine. It crystallizes in the monoclinic space group, P21/n. The effect of C-Br group on the crystal structure of TBHQ has been investigated. Its role in causing green luminescence in Ptychodera flava has been investigated.
Applicazioni
Tetrabromohydroquinone may be used in the synthesis of thermoresponsive branched oligoethylene glycol dendrimers.

Three interesting thermoresponsive branched oligoethylene glycol dendrimers based on tetrabromohydroquinone were efficiently synthesized from tetrabromohydroquinone and three different oligoethylene glycol derivatives. By visual inspection, all these dendrimers are water-soluble at room temperature. The thermoresponsive behaviors were investigated by using UV/vis

2,3,5,6-Tetrabromohydroquinone was isolated as a luminous substance from Ptychodera flava. This compound emitted light after addition of hydrogen peroxide under basic conditions. Since hydroquinone had no fluorescence, further investigation by spectral analysis revealed that riboflavin was the only possible light
