In the intricate world of chemistry, accurate identification of compounds is fundamental. The Chemical Abstracts Service (CAS) Registry Number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. For procurement professionals, R&D scientists, and anyone involved in sourcing chemicals, understanding and utilizing CAS numbers is critical for accuracy, compliance, and efficiency. Let's explore the significance of CAS numbers, using Benzene-1,3,5-triylhexabenzoic Acid (CAS: 1228047-99-1) as an example.

A CAS number consists of three parts separated by hyphens: the first two or three digits, a hyphen, the next two digits, a hyphen, and finally, the single check digit. The number itself has no inherent chemical significance but serves purely as a unique identifier, akin to a social security number for chemicals. For instance, Benzene-1,3,5-triylhexabenzoic Acid is universally identified by CAS 1228047-99-1, regardless of trade names or synonyms used by different companies.

When you intend to buy a specific chemical, using its CAS number is the most precise way to communicate your needs to a manufacturer or supplier. This eliminates ambiguity and ensures that you are requesting the correct substance. For example, if you are searching for high-purity intermediates, specifying the CAS number along with desired purity (e.g., 97% min for Benzene-1,3,5-triylhexabenzoic Acid) ensures you receive exactly what you need.

Furthermore, CAS numbers are vital for regulatory compliance, safety data sheets (SDS), and inventory management. They are used by governmental agencies, research institutions, and chemical companies worldwide to track chemicals, manage hazardous materials, and facilitate international trade. When engaging with a supplier, especially one in China, ensuring they provide accurate CAS numbers with their product listings and documentation is a mark of professionalism and transparency.

By accurately referencing CAS numbers, you not only streamline your purchasing process but also enhance safety and compliance.
