In the pharmaceutical industry, the quality of raw materials directly dictates the success of API synthesis. For manufacturers producing Entacapone, a vital medication for managing Parkinson's disease, the intermediate 3,4-Dihydroxy-5-nitrobenzaldehyde (CAS: 116313-85-0) is of utmost importance. This article provides a comprehensive overview of its properties and offers guidance on sourcing strategies for pharmaceutical professionals looking to purchase this critical chemical.

Understanding the Properties of 3,4-Dihydroxy-5-nitrobenzaldehyde

3,4-Dihydroxy-5-nitrobenzaldehyde is a chemical compound distinguished by its functional groups, which are essential for its role as a precursor in organic synthesis. It is typically supplied by manufacturers as a yellowish-green to yellowish-brown powder. Key physical and chemical properties, crucial for its application, include a melting point generally falling between 134°C and 145°C, and solubility in organic solvents such as methanol and ethanol. Its molecular formula is C7H5NO5, and its molecular weight is approximately 183.12 g/mol. The high purity, usually exceeding 99.0% as indicated by assay tests, is a critical parameter for pharmaceutical applications, ensuring minimal impurities in the final product. If you are considering to buy this intermediate, verifying these specifications is the first step.

The Crucial Role in Entacapone Synthesis

The significance of 3,4-Dihydroxy-5-nitrobenzaldehyde is profoundly linked to its function as a pivotal intermediate in the manufacturing process of Entacapone. Entacapone is a COMT inhibitor that enhances the efficacy of levodopa therapy in Parkinson's patients. The specific molecular structure of 3,4-Dihydroxy-5-nitrobenzaldehyde provides the necessary framework and reactive sites to facilitate the complex chemical reactions required to build the Entacapone molecule. Its consistent availability and quality are thus directly tied to the reliable production of this essential drug. Pharmaceutical companies must secure a dependable supply from qualified manufacturers to maintain their production pipelines.

Effective Sourcing Strategies for Buyers

When seeking to purchase 3,4-Dihydroxy-5-nitrobenzaldehyde, buyers should adopt a strategic approach. This involves identifying reputable manufacturers who specialize in pharmaceutical intermediates. Many leading suppliers are based in China, offering competitive pricing and a wide range of products. Key factors to consider when selecting a supplier include their manufacturing certifications, quality control procedures, ability to provide complete documentation (such as COA, MSDS, and potentially regulatory support documents), and their capacity to meet the required volumes and delivery timelines. Direct communication with potential manufacturers for quotations and samples is highly recommended to ensure the quality and suitability of the product for your specific needs.

Why Choose a Reputable Manufacturer?

Opting for a direct manufacturer rather than a third-party distributor often leads to better pricing, more direct technical support, and greater transparency in the supply chain. Reputable manufacturers understand the critical importance of lot-to-lot consistency and adherence to stringent quality standards demanded by the pharmaceutical sector. By partnering with such manufacturers, companies can ensure the reliable procurement of 3,4-Dihydroxy-5-nitrobenzaldehyde, thereby optimizing their Entacapone production process and ultimately contributing to patient well-being.
