In the intricate landscape of chemical commerce and scientific research, unique identifiers are crucial for clear communication and accurate tracking. The Chemical Abstracts Service (CAS) Registry Number is one such identifier, providing an unambiguous way to reference a specific chemical substance. For instance, CAS number 137863-89-9 uniquely identifies Methyl N-[(2'-Cyano[1,1'-biphenyl]-4-yl)methyl]-L-valinate, a vital compound in the pharmaceutical industry. Understanding these identifiers is fundamental for anyone involved in the pharmaceutical intermediate sourcing and chemical supply chain.
This particular CAS number is associated with a complex organic molecule that serves as a key intermediate in the synthesis of angiotensin II type 1 receptor antagonists. These drugs are essential for managing a range of cardiovascular conditions. The accuracy of the CAS number ensures that manufacturers and researchers obtain the correct compound for their precise applications, whether it’s for large-scale pharmaceutical intermediate synthesis or for detailed analytical studies, such as investigating the synthesis of valsartan impurity K.
The CAS system is a globally recognized standard, facilitating international trade and collaboration in the chemical sciences. When a company searches for a specific compound, using its CAS number is the most reliable method to avoid confusion and ensure product integrity. For suppliers of fine chemicals, correctly listing the CAS number for products like Methyl N-[(2'-Cyano[1,1'-biphenyl]-4-yl)methyl]-L-valinate is a mark of professionalism and commitment to accuracy.
The presence of this compound in various chemical databases, all referencing the same CAS number, underscores its importance. It signifies that this molecule has been well-characterized and its utility recognized within the scientific community. For those engaged in the synthesis of complex APIs, relying on the accurate CAS identification of intermediates like Methyl N-[(2'-Cyano[1,1'-biphenyl]-4-yl)methyl]-L-valinate is a non-negotiable aspect of quality assurance and regulatory compliance.
