In the intricate world of chemical sourcing, precision and unambiguous identification are paramount. The Chemical Abstracts Service (CAS) registry number, commonly known as the CAS number, serves as a unique identifier for chemical substances. For procurement managers, R&D scientists, and product formulators, understanding and utilizing CAS numbers is fundamental to ensuring accuracy, avoiding errors, and facilitating efficient global trade. This article highlights the importance of CAS numbers, using Pyridinium, 2-(2-acetyl-6-methoxy-3,9-dioxo-4,8-dioxa-2,10-diazaoctacos-1-yl)-1-ethyl-, Chloride (1:1), with CAS 100488-87-7, as a prime example.

The CAS number is a universally recognized identifier that distinguishes a specific chemical substance from all others. Unlike chemical names, which can be numerous, vary by region, or be subject to nomenclature changes, the CAS number remains constant. This global standardization is invaluable when sourcing materials internationally, especially from diverse manufacturing regions like China. When you search for a chemical intermediate, using its CAS number ensures that you are looking for the exact compound you need, eliminating potential confusion that can arise from common or trade names.

For a compound like Pyridinium, 2-(2-acetyl-6-methoxy-3,9-dioxo-4,8-dioxa-2,10-diazaoctacos-1-yl)-1-ethyl-, Chloride (1:1), the CAS number 100488-87-7 is the most reliable way to identify it across different databases, supplier catalogs, and regulatory documents. It allows manufacturers to precisely track production batches, maintain quality control records, and ensure that the synthesized product matches the intended specifications, such as its molecular formula C34H60N3O6 . Cl and molecular weight of 642.3097 g/mol.

When engaging with a chemical supplier, whether for research quantities or bulk purchases, always verify the CAS number. This simple step can prevent costly mistakes, such as ordering the wrong isomer or a structurally similar but functionally different compound. For procurement managers, confirming the CAS number on quotes and purchase orders is a standard best practice. It also aids in regulatory compliance, as many import/export regulations and safety data sheets (MSDS) are indexed by CAS number.

Manufacturers and suppliers leverage CAS numbers to streamline their own operations, from inventory management to technical support. When you inquire about purchasing chemicals, providing the CAS number allows the supplier to quickly access information regarding availability, pricing, and shipping options. For complex intermediates, having a clear CAS number ensures that the supplier understands your request for specific compounds, such as Pyridinium derivatives, and can provide an accurate quote for their sale.

In conclusion, the CAS number is a critical tool in the chemical industry. It provides a universal language for chemical identification, essential for accurate sourcing, quality assurance, and efficient global commerce. Always prioritize the use of CAS numbers, like 100488-87-7, when you buy or sell chemical intermediates to ensure precision and reliability in your operations.
