For professionals in the chemical industry, locating a dependable source for specialized intermediates is a constant challenge. This guide focuses on where to buy 2,2'-Diamino-biphenyl-4,4'-dicarboxylic acid (CAS 41738-56-1), a crucial compound in various synthesis applications, and what criteria to consider when selecting a supplier.

Understanding 2,2'-Diamino-biphenyl-4,4'-dicarboxylic Acid

Also known by its CAS number 41738-56-1 and chemical formula C14H12N2O4, this molecule is valued for its dual amine and dicarboxylic acid functionalities. These groups make it an ideal building block for polymers, pharmaceuticals, and other fine chemicals. Its consistent quality and purity are essential for successful downstream applications.

Key Factors When Buying Chemical Intermediates

When you decide to purchase 2,2'-Diamino-biphenyl-4,4'-dicarboxylic acid, several factors should guide your choice of supplier:

  • Manufacturer vs. Distributor: Purchasing directly from a manufacturer often provides better pricing and more direct quality control. Look for manufacturers with robust production capabilities, especially if you need to buy in bulk.
  • Purity and Specifications: Ensure the supplier offers the required purity level (e.g., 97% minimum) and provides detailed technical data sheets and Certificates of Analysis (CoA) upon request.
  • Supply Chain Reliability: A reliable supplier will have a stable production process and efficient logistics to ensure timely delivery. Inquire about their capacity and lead times.
  • Customer Service and Support: Responsive customer service is vital, particularly for technical inquiries or order modifications. A supplier that offers samples for testing is also a significant advantage.
  • Pricing: While cost is a factor, it should be balanced against quality and reliability. Compare quotes from multiple sources, but prioritize value over the lowest price alone.

Finding Suppliers in China

China is a prominent source for chemical intermediates. Many manufacturers there specialize in producing compounds like CAS 41738-56-1 with high quality and competitive pricing. When searching, use specific terms such as “buy 2,2'-Diamino-biphenyl-4,4'-dicarboxylic acid China” or “CAS 41738-56-1 supplier.” Engage with companies that demonstrate professionalism, transparency, and a commitment to quality assurance. Procuring from a trusted manufacturer will ensure you obtain the essential intermediate needed for your chemical synthesis needs.
