For professionals in the pharmaceutical, chemical, and materials science sectors, the reliable sourcing of key intermediates like 4-Iodoaniline (CAS 540-37-4) is fundamental to operational success. China has established itself as a global leader in chemical manufacturing, offering a vast landscape of potential suppliers. This guide aims to equip B2B buyers with the knowledge to effectively navigate this market and secure high-quality 4-Iodoaniline.

Understanding the Product: 4-Iodoaniline (CAS 540-37-4)

4-Iodoaniline is a white solid chemical compound with the CAS number 540-37-4. Its molecular formula is C6H6IN, and it is a crucial building block in organic synthesis. The iodine atom positioned para to the amino group on the benzene ring makes it highly reactive in various coupling reactions, enabling the formation of new carbon-carbon and carbon-heteroatom bonds. This versatility makes it indispensable for producing Active Pharmaceutical Ingredients (APIs), advanced materials, and agrochemicals. Researchers often seek to buy this intermediate for its predictable reactivity and its utility in creating complex molecular structures.

Key Factors When Selecting a Chinese Manufacturer:

When sourcing 4-Iodoaniline from China, a strategic approach to selecting a manufacturer is essential:

• Quality and Purity Verification: Insist on detailed Certificates of Analysis (CoAs) that clearly state the purity (typically 98% or higher for 4-iodoaniline) and assay results. Confirm if the manufacturer adheres to international quality management systems such as ISO 9001. Reputable manufacturers will provide comprehensive data to assure product quality.
• Production Capacity and Scalability: For industrial applications, the manufacturer's production capacity is crucial. Understand their ability to scale up from laboratory or pilot quantities to commercial volumes. This ensures that your supply needs can be met consistently as your projects grow. We, as a manufacturer, offer significant productivity and supply ability to meet diverse client demands.
• Supply Chain Management and Reliability: A stable supply chain is vital. Investigate the manufacturer’s raw material sourcing, production planning, and logistics capabilities. A manufacturer with a proven track record of timely delivery and consistent product availability is invaluable.
• Technical Expertise and Support: The ideal supplier offers more than just the product; they provide technical support. This can include assistance with product specifications, safe handling, and potential applications. For specialized needs, custom synthesis capabilities are a significant advantage.
• Competitive Pricing and Payment Terms: Obtain detailed quotes from multiple prospective suppliers. Compare not only the per-unit price but also consider minimum order quantities (MOQs), payment terms (e.g., L/C, T/T, D/P), and Incoterms (e.g., FOB, CIF, EXW). Understand the total cost of procurement.
• Communication and Transparency: Effective communication is key. Choose manufacturers who communicate clearly, promptly, and professionally. Transparency regarding production processes and lead times builds trust and facilitates a smoother transaction.

Navigating the Purchase Process:

Once you identify potential suppliers, the next steps involve:

• Requesting Samples: Always order samples to verify the quality and purity of the 4-iodoaniline firsthand before committing to a large purchase.
• Placing Orders: Clearly define your order requirements, including product specifications, quantity, packaging, and delivery date.
• Logistics and Shipping: Coordinate shipping arrangements, choosing the most suitable method (Ocean, Land, Air) and port based on your location and urgency.

By diligently following these guidelines, B2B buyers can confidently procure high-quality 4-Iodoaniline (CAS 540-37-4) from reputable Chinese manufacturers, ensuring the integrity and success of their critical chemical processes.
