For procurement managers and R&D scientists in the pharmaceutical industry, sourcing high-quality intermediates is paramount. One such crucial compound is 2-Ethyl-5-nitroaniline (CAS 20191-74-6). This article aims to guide B2B buyers through the process of procuring this vital chemical, emphasizing key considerations like purity, supplier reliability, and the benefits of sourcing from reputable manufacturers in China.

Understanding 2-Ethyl-5-nitroaniline (CAS 20191-74-6)

2-Ethyl-5-nitroaniline, also known by its synonyms such as 2-Ethyl-5-nitrobenzenamine, is a key organic intermediate. Its chemical structure and properties make it indispensable in various synthetic pathways. In the pharmaceutical sector, it is particularly recognized for its role as an intermediate in the synthesis of Active Pharmaceutical Ingredients (APIs), most notably Pazopanib. The demand for high-purity 2-Ethyl-5-nitroaniline is driven by the stringent quality requirements of pharmaceutical production.

Key Considerations for Procurement

When looking to buy 2-Ethyl-5-nitroaniline, several factors are critical:

  • Purity and Quality: Pharmaceutical applications demand a high level of purity, typically 98% or higher. Ensure that any potential supplier can provide Certificates of Analysis (CoA) that clearly state the purity and impurity profiles. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. prioritize these standards.
  • Supplier Reliability: A consistent and stable supply is crucial for uninterrupted production. Partnering with established manufacturers and suppliers in China, who have a proven track record, can mitigate supply chain risks. Look for suppliers who can offer bulk supply and contract manufacturing services.
  • Pricing and Quotation: Obtaining a competitive price quote for 2-Ethyl-5-nitroaniline is essential for cost management. It's advisable to solicit quotes from multiple reputable suppliers to ensure you are getting the best value. Consider the total cost of ownership, including shipping and potential import duties.
  • Regulatory Compliance: Ensure that the supplier adheres to relevant industry regulations and quality management systems, such as ISO certifications. This provides an added layer of assurance regarding product quality and safety.

Why Source from China?

China has emerged as a global hub for fine chemical and pharmaceutical intermediate manufacturing. The country boasts a vast network of highly capable manufacturers and suppliers who offer a compelling combination of quality, scalability, and cost-effectiveness. For B2B buyers seeking to purchase 2-Ethyl-5-nitroaniline, a Chinese manufacturer can often provide substantial advantages, including access to advanced production technologies and a streamlined export process.

Finding Your Ideal Supplier

When searching for a reliable 2-Ethyl-5-nitroaniline supplier, consider companies that specialize in pharmaceutical intermediates and have a strong online presence detailing their product offerings, capabilities, and customer service. Engaging with a direct manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. allows for more direct communication, better pricing, and a deeper understanding of the product's origin and quality control measures.

In conclusion, for pharmaceutical companies and R&D institutions, securing a consistent supply of high-quality 2-Ethyl-5-nitroaniline is a strategic imperative. By focusing on purity, supplier reliability, and understanding the benefits of sourcing from China, B2B buyers can effectively meet their material needs and drive innovation in drug development.
