In the chemical industry, precision and unambiguous identification are critical for effective communication and procurement. This is where CAS Registry Numbers (CAS RNs) play an indispensable role. A CAS number, such as 128607-22-7, is a unique numerical identifier assigned to a specific chemical substance. For professionals in R&D, procurement, and manufacturing, understanding the significance of these numbers is fundamental to successful operations.
The CAS number 128607-22-7 specifically refers to Ethanol, 2-[4-[(1Z)-4-chloro-1,2-diphenyl-1-buten-1-yl]phenoxy]-. When a buyer wishes to purchase this compound, using its CAS number is the most reliable way to ensure they are obtaining the exact substance required. This avoids confusion with similar compounds or variations in nomenclature. For manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., clearly listing the CAS number for products like this 99% pure intermediate, with a molecular weight of 378.89 g/mol, is standard practice to facilitate accurate customer orders.
The importance of CAS numbers extends beyond simple identification. They are vital for regulatory compliance, safety data sheet (SDS) referencing, and literature searches. When conducting research or looking to buy a specific chemical, starting with the CAS number ensures that all information retrieved pertains to the correct compound. This is particularly true for specialized intermediates used in pharmaceutical synthesis, where minor structural differences can have significant implications for reactivity and biological activity.
For procurement managers, specifying the CAS number in purchase orders guarantees that the correct material is ordered, thus preventing costly errors. It streamlines the procurement process and reduces the risk of receiving incorrect or substandard materials. A supplier’s ability to accurately provide and reference CAS numbers, like for Ethanol, 2-[4-[(1Z)-4-chloro-1,2-diphenyl-1-buten-1-yl]phenoxy]-, is often a good indicator of their professionalism and attention to detail.
In summary, CAS numbers are the universal language of chemical identification. Properly utilizing and understanding these identifiers, like the CAS 128607-22-7 for a key pharmaceutical intermediate, is crucial for accuracy, safety, and efficiency in all aspects of the chemical industry. Always ensure your supplier prominently features the correct CAS number for the products you need.
