|  |  | 1,2,4-TRIBROMOBENZENE Usage And Synthesis | 
 | Chemical Properties | WHITE CRYSTALLINE POWDER |  | Uses | 1,2,4-tribromobenzene is used in the synthesis of hyper branched poly(p-phenylene ethynylenes). It is used as cross-linking reagent during Pd-catalyzed cross-coupling of 2,5-diiodo-4-[(2-ethylhexyl)oxy]methoxybenzene and 1,4-diethynyl-2,5-bis-(octyloxy)benzene. It is a compound commonly used in organic synthesis reactions. |  | General Description | 1,2,4-tribromobenzene on photochemical dehalogenation in open-air solutions of acetonitrile yields 1,4-dibromobenzene, 1,3-dibromobenzene and 1,2-dibromobenzene. |
