In the complex and highly regulated pharmaceutical industry, precision and accuracy are non-negotiable. Chemical Abstract Service (CAS) Registry Numbers are fundamental to achieving this precision, serving as unique identifiers for chemical substances. For R&D scientists, formulation chemists, and procurement managers, understanding and correctly utilizing CAS numbers is essential when sourcing pharmaceutical intermediates and raw materials.
A CAS number is a unique numerical identifier assigned to a specific chemical substance, regardless of its common name or trade name. For instance, (E)-1-[1-(2-Hydroxyphenyl)-2-(methylthio)ethenyl]-1H-imidazole is assigned the CAS number 138206-46-9. This standardization ensures that there is no ambiguity when referring to a particular compound. When you are looking to buy a specific chemical, using its CAS number in your search query is the most reliable way to find exactly what you need and to communicate that need to suppliers accurately.
The importance of CAS numbers extends to quality assurance and regulatory compliance. When a supplier provides a Certificate of Analysis (CoA) for a product, the CAS number is always listed. This confirms that the reported specifications, such as purity (e.g., 97% min for CAS 138206-46-9), refer to the correct chemical entity. For manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., accurately listing the CAS number for each product, including (E)-1-[1-(2-Hydroxyphenyl)-2-(methylthio)ethenyl]-1H-imidazole, is a critical part of our commitment to transparency and product traceability.
When conducting literature reviews, patent searches, or comparing product offerings from different manufacturers, relying on CAS numbers eliminates confusion arising from synonyms or brand-specific nomenclature. For procurement managers, this means a more efficient and less error-prone sourcing process. You can confidently request quotes for specific CAS numbers, knowing that you are receiving offers for the intended chemical intermediate.
In summary, CAS numbers are indispensable tools in the chemical and pharmaceutical landscape. They are the universal language for chemical substances, facilitating accurate identification, reliable sourcing, and robust quality management. If your work involves chemicals, make it a practice to always use and verify the CAS number when you buy or sell. For your needs regarding CAS 138206-46-9, ensure your inquiries are precise by including this vital identifier.
