In the complex world of chemical procurement, accuracy and reliability are paramount. For professionals in research and development, manufacturing, and quality control, identifying the correct chemical substance is the first and most crucial step. This is where the Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, plays an indispensable role. A CAS number is a unique numerical identifier assigned to a specific chemical substance, acting as a universal language that transcends nomenclature variations and country-specific naming conventions.

Each CAS number is a string of digits separated by hyphens, such as 123640-38-0 for 2,6-bis(pyrazol-1-yl)pyridine. This number is assigned to a distinct chemical entity, whether it’s an element, isotope, ion, radical, or compound. The CAS Registry is the most comprehensive and authoritative source of chemical substance information globally. Using CAS numbers ensures that you are sourcing precisely the chemical you intend to purchase, preventing costly errors and ensuring the integrity of your processes.

For industries such as pharmaceuticals, agrochemicals, and advanced materials, the specificity of CAS numbers is vital. Take, for example, 2,6-bis(pyrazol-1-yl)pyridine. When you search for this compound to use as a pharmaceutical intermediate or a component in dye-sensitized solar cells, referencing its CAS number (123640-38-0) guarantees that suppliers understand precisely which chemical you require. This facilitates clear communication and accurate order fulfillment.

When you are ready to buy, looking for suppliers that prominently display the CAS number alongside the chemical name is a good practice. It indicates a level of professionalism and adherence to industry standards. As a trusted manufacturer and supplier of specialty chemicals from China, we ensure that all our product listings, including that of 2,6-bis(pyrazol-1-yl)pyridine, are clearly identified by their CAS numbers. This transparency helps our B2B clients confidently purchase the exact chemicals they need for their applications.

By prioritizing the use of CAS numbers in your sourcing process, you can significantly reduce the risk of misidentification and ensure you are obtaining high-quality materials from reliable manufacturers. We are here to provide you with the precise chemical intermediates, identified by their CAS numbers, that will support your innovation and production needs.
