In the intricate landscape of chemical synthesis, the quality and specifications of raw materials directly influence the success of research and manufacturing. 4-Bromo-2,5-difluoronitrobenzene (CAS: 167415-27-2) is a key intermediate that demands careful consideration of its purity, physical properties, and sourcing. This article delves into these aspects, providing valuable information for procurement specialists and R&D scientists seeking to buy this compound.

Understanding the Specifications: Purity and Properties

4-Bromo-2,5-difluoronitrobenzene is most commonly available with a minimum purity of 97% or 98% as determined by Gas Chromatography (GC). Higher purity grades may be available for highly specialized applications. Key physical properties include:

  • Appearance: Typically a light yellow solid to crystalline powder. Variations in color (e.g., yellow to green) can sometimes be observed depending on trace impurities, but the material should be consistent.
  • Melting Point: Generally falls in the range of 55-58°C, indicating a stable solid form at room temperature.
  • Molecular Formula: C6H2BrF2NO2
  • Molecular Weight: Approximately 237.99 g/mol.

These specifications are crucial for ensuring predictable reactivity and minimizing unwanted side reactions in complex synthetic routes, especially when used as a pharmaceutical intermediate or in agrochemical formulations. A reliable manufacturer will provide a detailed Certificate of Analysis (CoA) with each batch, confirming these critical parameters.

Factors Influencing Price and Procurement

The price of 4-Bromo-2,5-difluoronitrobenzene is influenced by several factors, including the purity grade, order volume, and global market demand. As a specialized chemical intermediate, its cost reflects the complex synthesis processes involved. For R&D purposes, smaller quantities may have a higher per-gram cost, while bulk purchases from a reputable supplier in China often offer significant cost savings. When requesting a quote, it's advisable to specify the exact quantity and purity required.

Sourcing from China: Advantages and Considerations

When you aim to purchase 1-bromo-2,5-difluoro-4-nitrobenzene, exploring Chinese chemical manufacturers can be highly beneficial. These suppliers often have advanced manufacturing capabilities and can offer competitive pricing due to economies of scale. However, it is imperative to partner with established companies that have a strong track record for quality control and reliable delivery. Due diligence, including checking for quality certifications and customer testimonials, is key to securing a dependable supply chain. Engaging with a trusted Chinese supplier ensures you receive the necessary intermediate efficiently and cost-effectively, supporting your product development and manufacturing needs.

In conclusion, understanding the purity, properties, and pricing structures of 4-Bromo-2,5-difluoronitrobenzene is vital for successful chemical synthesis. By carefully selecting your supplier and obtaining accurate quotes, you can ensure the quality and cost-effectiveness needed for your projects.
