For procurement managers and research scientists in the chemical and pharmaceutical industries, identifying reliable sources for critical intermediates is paramount. 3,6-Dibromophenanthrene (CAS 174735-02-5) stands out as a versatile building block with significant applications in advanced organic synthesis and material science. Understanding its properties, synthesis routes, and how to effectively buy it can streamline your R&D and production processes.

Understanding 3,6-Dibromophenanthrene: Properties and Synthesis

3,6-Dibromophenanthrene is a dibrominated derivative of phenanthrene, a polycyclic aromatic hydrocarbon. Its molecular formula is C14H8Br2, with a molecular weight of approximately 336.02 g/mol. This compound typically presents as a solid, with reported melting points around 188-191°C. Its structure, featuring bromine atoms at the 3 and 6 positions of the phenanthrene core, makes it particularly amenable to further functionalization.

The synthesis of 3,6-Dibromophenanthrene can be achieved through several methods. A common approach involves the direct bromination of phenanthrene under controlled conditions to ensure regioselectivity. Alternatively, it can be synthesized through the transformation of related phenanthrene derivatives. For instance, the synthesis of its quinone analogue, 3,6-Dibromo-phenanthrenequinone (CAS 53348-05-3), involves the oxidation of phenanthrenequinone with reagents like chromium trioxide in acetic acid, or direct bromination of phenanthrene-9,10-quinone. As a buyer, you would look for manufacturers who can consistently deliver this compound with high purity, typically 97% minimum, to ensure successful downstream reactions.

Key Applications Driving Demand

The significance of 3,6-Dibromophenanthrene in modern chemistry lies in its utility as a versatile intermediate. One of its primary applications is in macrocyclization reactions, particularly in the synthesis of [n]cyclo-3,6-phenanthrenylenes. These reactions, often nickel-mediated Yamamoto-type couplings, allow for the creation of complex macrocyclic structures with multiple phenanthrene units. These macrocycles are of great interest in supramolecular chemistry and material science.

Furthermore, the bromine functional groups on 3,6-Dibromophenanthrene make it an excellent substrate for various cross-coupling reactions, such as Suzuki, Stille, and Sonogashira couplings. These reactions are fundamental for building extended π-conjugated systems and functionalizing the phenanthrene core, leading to novel materials for optoelectronics, organic electronics, and potentially as pharmaceutical intermediates. Researchers often search for this chemical when looking to buy precursors for OLED materials or specialized dyes.

Sourcing and Procurement Considerations

When looking to purchase 3,6-Dibromophenanthrene, understanding supplier capabilities is key. Procurement managers should seek manufacturers who can offer detailed specifications, Certificates of Analysis (CoA), and reliable supply chains. For international buyers, sourcing from China offers competitive pricing and access to a vast chemical manufacturing base. When inquiring about 3,6-Dibromophenanthrene price, it's important to compare quotes from reputable suppliers who can guarantee product quality and timely delivery. Always check for product availability in grams to tons, depending on your project scale.
