In the precise world of chemical research and commerce, accurate identification is paramount. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves as a unique, unambiguous identifier for chemical substances. For anyone involved in sourcing or specifying chemicals, understanding and utilizing CAS numbers is fundamental. For instance, identifying 4-(3-bromo-5-(pyridin-4-yl)phenyl)pyridine by its CAS number, 361366-74-7, ensures that the correct compound is being discussed and procured.

A CAS number is a string of digits, separated by hyphens, that uniquely identifies a specific chemical compound. It is assigned by the CAS, a division of the American Chemical Society. Unlike chemical names, which can vary in nomenclature (e.g., IUPAC versus common names) or structural formulas, a CAS number is universally recognized. This standardization is incredibly valuable for procurement managers, R&D scientists, and product formulators who need to accurately order and track chemicals like pyridine derivatives.

When you search for a chemical, using its CAS number is often the most efficient and error-proof method. For example, when looking to buy 4-(3-bromo-5-(pyridin-4-yl)phenyl)pyridine, entering '361366-74-7' into a supplier's search engine (like ours) or database will directly lead to the correct product. This eliminates ambiguity, especially with compounds that have multiple synonyms or complex structures. It also ensures that information regarding purity, availability, and pricing from a specific manufacturer is accurate for the intended substance.

The importance of CAS numbers is amplified when dealing with international suppliers, particularly from regions like China, where chemical nomenclature might differ. A shared CAS number bridges these linguistic and naming conventions, ensuring clear communication regarding chemical specifications. Whether you are researching potential applications for a chemical intermediate or placing a bulk order for your manufacturing process, always verify the CAS number to guarantee you are getting the exact material needed, such as the highly specific 4-(3-bromo-5-(pyridin-4-yl)phenyl)pyridine.

In essence, CAS numbers are the universal language of chemical identification. They are essential tools for anyone working with chemicals, from laboratory synthesis to industrial-scale procurement. By consistently using CAS numbers, professionals can ensure accuracy, avoid costly errors, and efficiently source critical compounds like 4-(3-bromo-5-(pyridin-4-yl)phenyl)pyridine from reliable manufacturers and suppliers globally.
