Navigating the global chemical market for essential raw materials can be a complex task for procurement managers and R&D scientists. Dodecyltrimethylammonium Bromide (CAS 1119-94-4), a versatile cationic surfactant, is a prime example of a chemical that is widely sought after for its applications in diagnostics, pharmaceuticals, and organic synthesis. For many international buyers, China represents a significant source for this compound, offering competitive pricing and substantial production capacity. This guide aims to provide insights for effectively sourcing DTAB from Chinese manufacturers and suppliers.

Understanding the product is the first step. Dodecyltrimethylammonium Bromide, appearing as a white to slightly yellow powder, is known for its surfactant properties and its utility as a phase transfer catalyst. Its chemical formula is C15H34BrN, with a molecular weight of approximately 308.34 g/mol. Key specifications often include a purity of 99% or higher, with a melting point around 246°C. When you intend to buy this chemical, confirming these specifications with your potential supplier is crucial to ensure it meets your application’s demands, whether for precise diagnostic reagent formulation or efficient catalytic processes.

When considering Chinese manufacturers and suppliers for Dodecyltrimethylammonium Bromide, several factors come into play. Price is often a major driver, and China's manufacturing infrastructure generally allows for competitive cost structures. However, it is vital to balance cost with quality and reliability. A lower price might sometimes indicate compromises in purity, quality control, or production standards. Therefore, seeking out established suppliers with a good track record and certifications is advisable.

To effectively purchase DTAB, look for suppliers who offer:

  • Detailed Product Specifications and CoA: A reputable manufacturer will readily provide a Certificate of Analysis (CoA) for each batch, detailing purity, physical properties, and any relevant analytical data.
  • Consistent Quality: Ensure the supplier has robust quality control systems to guarantee batch-to-batch consistency, which is critical for reproducible results in R&D and manufacturing.
  • Reliable Supply Chain and Logistics: A good supplier will have established processes for packaging, handling, and shipping, ensuring timely delivery and adherence to international transport regulations.
  • Good Communication and Customer Service: Responsive communication is key when dealing with international suppliers. Clear communication channels help in resolving queries and ensuring a smooth transaction.

Leveraging platforms like Alibaba or direct inquiries to known chemical export companies can be starting points. However, due diligence is essential. Requesting samples for initial testing is a standard practice to verify product quality before committing to larger orders. Many Chinese suppliers are accustomed to international business practices and are prepared to facilitate this process.

For applications in diagnostic kits, the purity of Dodecyltrimethylammonium Bromide is non-negotiable. Similarly, in advanced organic synthesis, impurities can inhibit catalytic activity or lead to unwanted side reactions. Therefore, thoroughly vetting your potential supplier and understanding their production capabilities is as important as the price point.

In summary, sourcing Dodecyltrimethylammonium Bromide (CAS 1119-94-4) from China can be a strategic move for businesses looking for quality and value. By focusing on supplier credibility, product specifications, and a clear understanding of your application's requirements, you can successfully buy this essential chemical intermediate and build a strong, reliable supply chain. Remember, a proactive approach to supplier evaluation ensures that you secure a high-quality product that meets all your technical needs.
