In the complex world of chemistry, precise identification of compounds is fundamental. Whether you're a researcher in a lab, a procurement manager for a pharmaceutical company, or a chemist optimizing a synthesis, knowing the exact chemical you need is crucial. This is where Chemical Abstracts Service (CAS) numbers come into play. These unique numerical identifiers are the universal language for chemical compounds, ensuring clarity and accuracy in sourcing and communication.
What is a CAS Number?
A CAS Registry Number® (CAS RN®) is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. It consists of three parts separated by hyphens, with the first part ranging from one to seven digits, the second part from two to eight digits, and the third part being a single check digit. For example, Desbenzyl Donepezil Hydrochloride is identified by the CAS number 120013-39-0. This number is assigned by the Chemical Abstracts Service, a division of the American Chemical Society. Crucially, a CAS number is assigned to only one chemical substance, regardless of how many different names it might have. This eliminates ambiguity when referring to specific compounds.
Why are CAS Numbers Essential for Sourcing?
For businesses and researchers looking to buy chemical compounds, CAS numbers are indispensable tools. Consider the process of searching for Desbenzyl Donepezil Hydrochloride. You might find it listed under various synonyms such as 5,6-Dimethoxy-2-(piperidin-4-ylmethyl)-1-indanone hydrochloride. By using the CAS number 120013-39-0, you can bypass potential naming confusion and directly identify the exact compound you require. This is particularly important when dealing with international suppliers, where language barriers might otherwise complicate precise identification.
Benefits for Buyers and Manufacturers
Manufacturers and suppliers, like those providing Desbenzyl Donepezil Hydrochloride, prominently feature the CAS number in their product listings. This helps them attract buyers who are searching for specific chemicals. For instance, a procurement manager looking for a supplier of 'Desbenzyl Donepezil Hydrochloride CAS 120013-39-0' can quickly find relevant results and initiate an inquiry for pricing and bulk purchase options.
In Conclusion
CAS numbers are more than just a series of digits; they are the backbone of chemical identification and trade. Understanding and utilizing these unique identifiers is a fundamental skill for anyone involved in chemical sourcing and research. When you need to buy a specific chemical, always rely on its CAS number to ensure you are getting precisely what you require, from the right manufacturer, with the expected quality and specifications.
