Bromopentamethylbenzene, identified by CAS number 5153-40-2, is an organic compound that merits close attention from professionals in chemistry and related fields. Its molecular structure, characterized by a benzene ring heavily substituted with five methyl groups and one bromine atom, dictates its unique properties and broad utility. Understanding these characteristics is key for anyone looking to buy or utilize this chemical effectively.

Physically, Bromopentamethylbenzene typically presents as a white to off-white crystalline powder or solid. Its melting point, around 161-162°C, indicates its solid state at room temperature. As an aromatic hydrocarbon with multiple methyl substituents and a halogen, it exhibits low solubility in water but is generally soluble in common organic solvents. These properties are important considerations for chemists when planning reaction conditions or purification steps.

The chemical reactivity of Bromopentamethylbenzene is largely governed by the bromine substituent. This halogen atom can be displaced through nucleophilic substitution reactions, or it can be involved in various metal-catalyzed cross-coupling reactions, such as the Suzuki, Stille, or Heck reactions. These transformations are foundational in modern organic synthesis, enabling the construction of complex carbon frameworks and the introduction of diverse functional groups. This makes it a highly sought-after intermediate for creating sophisticated molecules.

The applications of Bromopentamethylbenzene are diverse, spanning organic synthesis, the development of pharmaceutical intermediates, and as a component in materials science research. Its highly substituted nature can impart unique steric and electronic effects, influencing the outcomes of chemical reactions and the properties of resulting materials. For example, its use as a precursor for advanced polymers or specialty organic compounds is an area of ongoing research and development.

For researchers and industrial buyers, sourcing this chemical from reliable manufacturers is essential. China offers a significant supply base for compounds like Bromopentamethylbenzene (CAS 5153-40-2), with many manufacturers providing high-purity grades at competitive prices. When looking to buy, it's advisable to engage with suppliers who can provide detailed specifications, including physical appearance and solubility data, along with consistent quality and prompt delivery. This ensures that your synthesis or research projects proceed smoothly and efficiently.

In summary, Bromopentamethylbenzene is a valuable organic intermediate with well-defined properties and significant utility in synthesis. By understanding its characteristics and sourcing it from reputable Chinese manufacturers, professionals can effectively integrate this compound into their research and production workflows.
