2,4,6-tribromo-1,3,5-trimethylbenzene; CAS No.: 608-72-0;2,4,6-tribromo-1,3,5-trimethylbenzene. PROPERTIES: 2,4,6-tribromo-1,3,5-trimethylbenzene is a highly brominated and methylated aromatic compound with molecular formula C9H9Br3. It typically exists as a colorless to pale yellow crystalline solid with a melting point of approximately 65-70 C. The compound has low water solubility but dissolves in organic solvents like hexane or toluene. It exhibits moderate thermal stability but may release toxic bromine vapors when exposed to high temperatures or flames. Proper storage involves keeping it in tightly sealed containers below 25 C, away from heat sources and incompatible materials. APPLICATIONS: In organic synthesis, this compound serves as a building block for creating sterically hindered aromatic systems. The tribromo functionality provides significant electron-withdrawing effects, while the trimethyl substituents offer steric protection (The Journal of Organic Chemistry). In materials science, the compound contributes to the development of organic semiconductors with improved charge transport properties, where the electron-withdrawing bromine atoms modulate electronic characteristics (Journal of Materials Chemistry C). Its structure makes it suitable for creating self-assembled monolayers on surfaces, useful in nanotechnology applications where steric effects influence assembly and stability (Langmuir).
