In the realm of specialty chemicals manufacturing, the availability of high-quality building blocks is fundamental to creating innovative products. CAS 23703-22-2, commonly known as 1-Bromo-4-hexylbenzene, is a prime example of such a critical organic intermediate. Its unique structure and reactivity make it indispensable for a variety of advanced synthesis applications, particularly in the electronics and pharmaceutical sectors. Understanding its role and how to procure it efficiently is vital for any manufacturer or research scientist.

Understanding CAS 23703-22-2: Structure and Properties

1-Bromo-4-hexylbenzene is an organobromine compound with the chemical formula C12H17Br and a molecular weight of 241.17 g/mol. The molecule features a benzene ring substituted with a bromine atom at one position and a hexyl (six-carbon alkyl) chain at the para position. This arrangement is significant for several reasons:

  • Reactive Bromine Atom: The C-Br bond is susceptible to nucleophilic substitution and is highly reactive in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira). This allows for the efficient formation of new carbon-carbon bonds, essential for building complex molecular structures.
  • Lipophilic Hexyl Chain: The hexyl group enhances the molecule's solubility in organic solvents and can influence the physical properties of the final products, such as melting point, boiling point, and phase behavior, which is critical in materials science.

Applications in Specialty Chemicals

The versatility of 1-Bromo-4-hexylbenzene makes it a sought-after intermediate in numerous high-value applications:

  • Liquid Crystals: It is a key precursor for synthesizing mesogenic compounds used in liquid crystal displays (LCDs) and other photonic devices. The hexyl chain often contributes to the formation and stability of desired liquid crystalline phases.
  • Organic Electronics: This intermediate is utilized in the synthesis of organic semiconductors, charge transport materials, and polymers for organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and field-effect transistors (OFETs).
  • Pharmaceuticals: As a pharmaceutical intermediate, it serves as a building block for active pharmaceutical ingredients (APIs). Its reactive bromine allows for its incorporation into diverse drug scaffolds through various synthetic routes.
  • Agrochemicals: In some cases, it can be used as an intermediate in the synthesis of crop protection agents.

Procuring CAS 23703-22-2: Manufacturer Insights

For businesses looking to buy 1-Bromo-4-hexylbenzene, sourcing from reliable manufacturers, particularly those in China, offers competitive pricing and accessibility. When procuring this chemical, consider these important factors:
