For professionals in the chemical industry, sourcing high-quality intermediates is paramount to successful research and manufacturing. 2-Bromonaphthalene, identified by CAS number 580-13-2, stands out as a remarkably versatile building block. Its unique chemical structure, featuring a bromine atom attached to the naphthalene core, makes it an indispensable component in a wide array of organic synthesis pathways. This article aims to guide procurement managers and R&D scientists in understanding the significance of 2-Bromonaphthalene and how to effectively source it from reliable manufacturers.

The Chemical Profile of 2-Bromonaphthalene
2-Bromonaphthalene typically presents as a colorless to pale yellow crystalline solid or liquid, depending on ambient temperature and specific purity levels. With a high purity often exceeding 98-99%, it ensures predictable and efficient reactions. Its key role lies in its reactivity, particularly in cross-coupling reactions such as Suzuki, Stille, and Heck couplings, which are fundamental for constructing complex organic molecules. The naphthalene moiety itself provides a stable aromatic platform, while the strategically placed bromine atom acts as an excellent leaving group or activation site for further functionalization. This makes it a preferred choice for synthesizing advanced materials, pharmaceuticals, and specialized dyes.

Applications Driving Demand
The demand for 2-Bromonaphthalene is significantly driven by its critical applications across several key sectors:

  • Pharmaceutical Intermediates: It serves as a crucial building block in the synthesis of various pharmaceutical compounds. Researchers and manufacturers often look to buy 2-Bromonaphthalene to create complex molecular structures that form the basis of new drug candidates. The precise introduction of the naphthalene unit is vital for the efficacy and targeting of certain therapeutic agents.
  • Dyes and Pigments: In the dye industry, 2-Bromonaphthalene is utilized as a precursor for naphthalene-based dyes. The presence of the bromine atom can influence the color properties and stability of the final dye, making it a valuable component for creating vibrant and durable colorants. Sourcing this dye intermediate from a reputable manufacturer in China ensures consistent quality for your production lines.
  • Materials Science: The compound is increasingly important in the field of materials science, particularly in the development of organic electronic materials such as OLEDs (Organic Light-Emitting Diodes) and organic photovoltaic cells. Its structure contributes to the electronic and optical properties of these advanced materials.
  • General Organic Synthesis: Beyond these specific fields, 2-Bromonaphthalene is a staple in many general organic synthesis laboratories for various transformations, including Grignard reagent formation and electrophilic aromatic substitutions.

Sourcing 2-Bromonaphthalene: What Buyers Need to Know
When looking to purchase 2-Bromonaphthalene, several factors are crucial for B2B procurement:

  • Purity: Aim for a minimum purity of 98%, with 99% or higher being ideal for demanding applications. This directly impacts reaction yields and the quality of the final product.
  • Supplier Reliability: Partnering with an established 2-Bromonaphthalene manufacturer or a trusted supplier is essential. Look for companies with strong quality control measures, certifications, and a proven track record in chemical production and export.
  • Pricing and Availability: Obtaining competitive prices for 2-Bromonaphthalene is key for cost-effective manufacturing. Understanding the production capacity and lead times from suppliers, especially those based in China, can streamline your procurement process.
  • Technical Support and Documentation: Reliable suppliers provide comprehensive technical data, including safety data sheets (SDS) and certificates of analysis (CoA), alongside responsive customer support.
