Pentamethylbenzene

Pentamethylbenzene is an organic compound with the chemical formula C11H16. It is a derivative of benzene, with five methyl groups attached to the benzene ring, and one hydrogen atom remaining. It is a white crystalline solid at room temperature. Pentamethylbenzene is soluble in organic solvents such as ethanol and ether but is practically insoluble in water. Its structure is symmetrical, belonging to the D5h point group. The compound can be synthesized through various organic reactions, including the Friedel-Crafts alkylation of benzene or other methylated benzenes. It is sometimes used as a precursor in the synthesis of more complex organic molecules and in research laboratories. Pentamethylbenzene can be oxidized to form pentamethylbenzoic acid. Its boiling point is approximately 231 degrees Celsius, and its melting point is around 50-52 degrees Celsius. It is not considered a hazardous substance under normal handling conditions, though standard laboratory precautions should always be observed.
