For pharmaceutical manufacturers and researchers, sourcing high-quality chemical intermediates is paramount to the success of drug discovery and development. 4-Nitrophthalic Anhydride (CAS: 5466-84-2) stands out as a critical building block, widely utilized in the synthesis of advanced pharmaceutical agents and specialty chemicals. This article aims to guide procurement managers and R&D scientists in understanding the importance of this compound and how to effectively source it from reliable manufacturers.

Understanding 4-Nitrophthalic Anhydride

4-Nitrophthalic Anhydride is an organic compound characterized by its phthalic anhydride structure with a nitro group attached. Its chemical formula is C8H3NO5, and it typically appears as a white to light yellow powder. With a purity level often exceeding 98%, it serves as an essential precursor in various complex organic synthesis reactions. Its significance is particularly noted in the pharmaceutical sector, where it functions as a key intermediate in the creation of Active Pharmaceutical Ingredients (APIs). For instance, it is instrumental in the synthesis of benzimidazole PARP inhibitors, a class of drugs showing promise in cancer therapy. Beyond pharmaceuticals, its utility extends to the creation of fluorescent dyes and isothiocyanate derivatives, valuable in diagnostic and research applications.

Why Choose a Reliable Supplier?

The efficacy and purity of the final product are directly influenced by the quality of the starting materials. For pharmaceutical applications, stringent quality control and consistent batch-to-batch uniformity are non-negotiable. Therefore, selecting a reputable manufacturer and supplier for 4-Nitrophthalic Anhydride is crucial. A reliable supplier will not only guarantee high purity but also provide comprehensive technical data, safety information (SDS), and certificates of analysis (CoA). Furthermore, they should offer competitive pricing and a stable supply chain, ensuring uninterrupted production.

Key Considerations When Buying 4-Nitrophthalic Anhydride

When looking to buy 4-Nitrophthalic Anhydride, consider the following:

  • Purity Levels: Ensure the supplier offers a purity of 98% or higher, as indicated by reliable analytical methods.
  • CAS Number Verification: Confirm the CAS number is 5466-84-2 to ensure you are obtaining the correct isomer.
  • Manufacturing Capabilities: Investigate the manufacturer's production capacity and quality management systems. Manufacturers in China are often competitive in terms of both price and production scale.
  • Technical Support: A good supplier will have knowledgeable technical staff who can assist with product-related queries and application support.
  • Logistics and Delivery: Understand their shipping capabilities and delivery times to meet your project timelines.
