In the complex world of chemical procurement, sourcing reliable intermediates like 4-Iodoaniline (CAS 540-37-4) is paramount for the success of pharmaceutical and fine chemical industries. For purchasing managers and R&D scientists, understanding the key factors when selecting a manufacturer and supplier can significantly impact project timelines and product quality. This article provides insights into navigating the market for this vital compound.

Understanding 4-Iodoaniline (CAS 540-37-4)

4-Iodoaniline, with its CAS number 540-37-4, is a halogenated aromatic amine that serves as a crucial building block in organic synthesis. Its molecular formula is C6H6IN, and it typically appears as a white solid with a melting point around 63-65°C. The presence of the iodine atom on the aniline ring makes it highly reactive in various coupling reactions, such as Suzuki-Miyaura, Heck, and Sonogashira couplings. This reactivity profile makes it indispensable for the synthesis of Active Pharmaceutical Ingredients (APIs), agrochemicals, and advanced materials.

Key Considerations for B2B Buyers

When seeking to buy 4-Iodoaniline, B2B buyers should prioritize several critical aspects:

  • Purity and Quality Control: The purity of 4-Iodoaniline directly influences the yield and efficacy of downstream products. Reputable manufacturers will provide detailed Certificates of Analysis (CoA) demonstrating purity levels, typically 98% or higher. Look for suppliers who adhere to international quality standards like ISO certifications.
  • Manufacturer Reliability: Partnering with an established manufacturer in China offers distinct advantages, including competitive pricing and scalable production capacity. A trustworthy supplier will have a transparent supply chain and robust production processes to ensure consistent product availability.
  • Supply Chain Stability: For ongoing projects, consistent and timely delivery is non-negotiable. A reliable supplier will have efficient logistics and inventory management to meet your demand for 4-Iodoaniline, preventing costly production delays.
  • Pricing and Cost-Effectiveness: While quality is paramount, cost remains a significant factor. Obtaining quotes from multiple suppliers and understanding market pricing for 4-Iodoaniline can help secure the best value without compromising on quality. Consider the total cost of ownership, including shipping and potential import duties.
  • Technical Support and Customization: Some suppliers offer technical support and custom synthesis services. If your project requires specific packaging, tailored purity levels, or derivatives of 4-Iodoaniline, these capabilities can be invaluable.

Sourcing Strategies from China

China has emerged as a global hub for fine chemical manufacturing, offering a wide range of suppliers for 4-Iodoaniline (CAS 540-37-4). When engaging with Chinese manufacturers and suppliers:

  • Thorough Due Diligence: Research potential suppliers by checking their company profiles, customer reviews, and product certifications. Online platforms and industry directories can be helpful resources.
  • Request Samples and Quotes: Always request samples for quality verification before placing a large order. Obtain detailed quotes that include product specifications, minimum order quantities (MOQ), payment terms, and Incoterms (e.g., FOB, CFR, CIF).
  • Clear Communication: Ensure clear and concise communication regarding your specific requirements, delivery timelines, and any technical specifications. Leveraging translation services or working with suppliers who have English-speaking representatives can facilitate smoother transactions.
  • Payment and Shipping: Familiarize yourself with common payment methods (L/C, T/T, PayPal) and shipping options (Ocean, Air, DHL, TNT) to ensure a secure and efficient transaction.

By focusing on these key aspects, B2B professionals can confidently source high-quality 4-Iodoaniline (CAS 540-37-4) from reliable manufacturers and suppliers in China, paving the way for successful chemical synthesis and product development.
