For pharmaceutical researchers and procurement managers, identifying a dependable source for critical chemical intermediates like Phenylbiguanide (CAS 102-02-3) is paramount. The quality and consistency of these building blocks directly impact the success of drug synthesis and the efficacy of the final pharmaceutical product. Understanding the key considerations when sourcing Phenylbiguanide from manufacturers, particularly those based in China, can significantly streamline your procurement process and ensure the integrity of your R&D pipeline.

Phenylbiguanide, identified by CAS number 102-02-3, is a compound valued for its role in organic synthesis, particularly within the pharmaceutical sector. Its chemical structure allows for versatile applications, serving as a key intermediate in the creation of various complex organic molecules. When purchasing this chemical, purity is a non-negotiable factor. Manufacturers often specify purity levels, with higher percentages (e.g., 98% or 99%) being preferred for sensitive pharmaceutical applications to minimize unwanted side reactions and by-products.

When searching for a Phenylbiguanide supplier, consider manufacturers that provide detailed product specifications, including molecular formula (C8H11N5), molecular weight (177.21), and melting point (typically 135-142 °C). Information regarding its form (powder to crystal) and storage conditions is also crucial for maintaining its quality. Working with a manufacturer that can provide Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS) instills confidence in the product's reliability.

The domestic market in China offers a robust network of chemical manufacturers. However, selecting the right partner requires due diligence. Look for suppliers with a proven track record, transparent business practices, and a commitment to quality control. Companies that offer competitive pricing for Phenylbiguanide, along with efficient shipping and customer support, are ideal. It is often beneficial to request a free sample of Phenylbiguanide before committing to bulk purchases, allowing you to test its suitability for your specific application.

For procurement managers, understanding the total cost of ownership is important. This includes not only the price of Phenylbiguanide but also shipping costs, potential import duties, and the lead time for delivery. Establishing a direct relationship with a manufacturer or their authorized distributor can often lead to better pricing and more predictable supply. Engaging with these suppliers for quotes early in your research phase can also help in budget planning.

In summary, sourcing high-purity Phenylbiguanide (CAS 102-02-3) from reputable manufacturers in China requires a focus on product specifications, quality assurance, and supplier reliability. By prioritizing these factors and potentially requesting samples, R&D scientists and procurement professionals can secure a consistent and high-quality supply of this vital pharmaceutical intermediate, ensuring the efficiency and success of their drug development endeavors.
