For R&D scientists and procurement managers in the advanced materials sector, sourcing high-quality chemical intermediates is paramount. Among these, 1,3-Bis(3-aminophenoxy)benzene (CAS 10526-07-5) stands out as a critical building block for synthesizing high-performance polymers, particularly polyimides (PI). This article serves as a comprehensive guide for professionals looking to purchase this vital compound, focusing on what to expect from Chinese manufacturers and suppliers.

Understanding 1,3-Bis(3-aminophenoxy)benzene

1,3-Bis(3-aminophenoxy)benzene is an aromatic diamine characterized by its unique ether linkages and amine functional groups. Its molecular structure (C18H16N2O2) endows it with exceptional thermal stability, excellent mechanical properties, and good dielectric characteristics when incorporated into polymer chains. This makes it indispensable for applications requiring materials that can withstand extreme conditions, such as in aerospace, electronics, and advanced coatings. When you buy 1,3-Bis(3-aminophenoxy)benzene, you are investing in the foundational component for these advanced materials.

Key Considerations When Purchasing from China: Purity and Specifications

For any B2B purchase of chemical intermediates, purity is non-negotiable. Reputable Chinese manufacturers of 1,3-Bis(3-aminophenoxy)benzene typically offer products with purity levels of 97% or even 98.0% (HPLC). When you contact a supplier for a quote, always verify the specified purity and the analytical methods used (e.g., HPLC, GC). Requesting a Certificate of Analysis (COA) with each batch is standard practice and crucial for quality assurance. Understanding the CAS number, 10526-07-5, ensures you are sourcing the exact compound required for your specific synthesis pathway.

Navigating the Supply Chain: Finding Reliable Manufacturers and Suppliers

The landscape of chemical manufacturing in China is vast, offering numerous options. For procurement managers, identifying reliable manufacturers and suppliers of 1,3-Bis(3-aminophenoxy)benzene is key. Look for companies that specialize in fine chemicals and intermediates, have a clear understanding of international trade (Incoterms like FOB, CFR, CIF), and offer robust customer support. Keywords such as 'buy 1,3-Bis(3-aminophenoxy)benzene China' or '10526-07-5 supplier' will help you find potential partners. Direct sourcing from a manufacturer can often yield better pricing and greater transparency. Companies that provide detailed product descriptions, safety data sheets (SDS), and prompt responses to inquiries are generally more trustworthy.

Pricing and Order Quantities

The price of 1,3-Bis(3-aminophenoxy)benzene can vary significantly based on purity, order volume, and the supplier. Generally, purchasing in larger quantities (e.g., kilograms) will result in a lower per-unit cost compared to smaller research quantities (grams). When you request a price, be prepared to discuss your projected annual volume. Minimum Order Quantities (MOQ) can range from grams for R&D purposes to several kilograms for pilot or commercial production. Comparative sourcing from multiple manufacturers is always recommended to secure the best price and terms.

Conclusion: Strategic Sourcing for Advanced Material Development

In summary, securing a consistent supply of high-purity 1,3-Bis(3-aminophenoxy)benzene (CAS 10526-07-5) from China is a strategic move for companies developing advanced materials. By focusing on purity, reliable manufacturers, and understanding pricing structures, procurement professionals can effectively source this essential intermediate. For your next requirement, consider partnering with established Chinese suppliers who can guarantee quality and competitive pricing, ensuring the success of your innovative material projects.
