For procurement managers and R&D scientists in the chemical industry, sourcing specialized compounds like CAS 38775-22-3, also known as C.I. Fluorescent Brightener 351 or 4,4'-Bis(2-sulfostyryl)biphenyl, requires a strategic approach. This high-performance optical brightener is integral to achieving superior whiteness and brightness in a multitude of industrial applications, from textiles and paper to detergents and plastics. Understanding the nuances of procurement is key to securing a consistent and cost-effective supply.

When looking to buy this critical ingredient, the first step is identifying reputable manufacturers and suppliers. China, in particular, has emerged as a significant hub for fine chemical production, offering competitive pricing and substantial supply capabilities. When you search for a 'manufacturer China' or 'supplier in China' for CAS 38775-22-3, you are likely to find several options. However, it’s vital to conduct due diligence. Look for suppliers with established certifications, positive customer reviews, and clear communication channels. Understanding their production capacity and quality control processes is also essential.

Pricing is another significant consideration for B2B purchasing. The price of CAS 38775-22-3 can vary based on quantity, purity, and market dynamics. Bulk orders typically command lower per-unit prices. Therefore, it is advisable to request a quote for your specific volume requirements. Engaging with a supplier early in your product development cycle can also help in negotiating favorable terms and ensuring long-term supply stability.

Beyond price, inquire about product specifications, packaging options, and delivery timelines. For instance, understanding the typical appearance (often a yellow powder) and physical state is important for handling and formulation. The supply ability, often listed in tons or kilograms per month, indicates the manufacturer's capacity to meet your demand. Reliable logistics and efficient shipping are also critical to avoid production delays.

In summary, sourcing 4,4'-Bis(2-sulfostyryl)biphenyl requires careful consideration of supplier reliability, competitive pricing, and product quality. By focusing on manufacturers who can guarantee consistent supply and adhere to high-quality standards, businesses can ensure their products benefit from the excellent whitening and brightening properties of this essential fluorescent brightener. Don't hesitate to reach out to leading suppliers for detailed product information and to secure your procurement needs.
