In the vast and complex world of chemistry, precise identification of substances is critical for research, safety, and commerce. The Chemical Abstracts Service (CAS) Registry Number, commonly known as the CAS number, is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. These numbers serve as an indispensable tool for chemists, researchers, and regulatory bodies to unambiguously identify and track specific chemical compounds. NINGBO INNO PHARMCHEM CO.,LTD. understands the crucial role of CAS numbers in the precise sourcing of chemicals.

Consider Ethyl 4,4-Difluorocyclohexanecarboxylate. This compound, a vital intermediate in various synthetic processes, is universally recognized by its CAS number: 178312-47-5. This unique identifier eliminates ambiguity, ensuring that researchers worldwide are referring to the exact same molecule, regardless of differences in common names, synonyms, or even misspellings. For example, searching for 'CAS 178312-47-5' will reliably yield information and product listings for Ethyl 4,4-Difluorocyclohexanecarboxylate, facilitating efficient procurement.

The importance of CAS numbers extends to safety and regulatory compliance. Material Safety Data Sheets (MSDS) and product labels invariably include the CAS number, allowing users to quickly access critical safety information, handling precautions, and hazard classifications. In international trade and chemical inventory management, the CAS number is essential for customs clearance, regulatory reporting, and ensuring compliance with global chemical regulations.

When sourcing chemicals, especially specialized intermediates like Ethyl 4,4-Difluorocyclohexanecarboxylate, using the correct CAS number is paramount. It ensures that you are ordering the specific chemical structure and purity required for your application. Reputable suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., prominently feature CAS numbers in their product listings and documentation, simplifying the procurement process for their clients and reducing the risk of errors.

The CAS Registry is continuously updated with new substances, making it a living database of the chemical universe. This ongoing effort ensures that as new compounds are synthesized and characterized, they receive a unique identifier, further solidifying the CAS number's role as the global standard for chemical nomenclature and identification. By utilizing CAS numbers effectively, researchers can navigate the vast chemical landscape with confidence and precision.

At NINGBO INNO PHARMCHEM CO.,LTD., we emphasize the use of CAS numbers to ensure accuracy and facilitate efficient transactions. Whether you are looking for specific fluorinated intermediates, pharmaceutical building blocks, or other fine chemicals, referencing the correct CAS number is the first step towards securing the precise materials needed for your research and production needs.
