In the precise world of chemical procurement and research, accuracy is non-negotiable. Every substance, from bulk industrial chemicals to specialized research intermediates, needs a definitive identifier. This is where the Chemical Abstracts Service (CAS) Registry Number, or CAS number, becomes indispensable. For professionals tasked with sourcing materials, understanding the significance of a CAS number is fundamental to ensuring the right compound is purchased, thereby safeguarding research integrity and operational efficiency.
A CAS number is a unique numerical identifier assigned to a specific chemical substance. It serves as a universal language, eliminating ambiguity that can arise from varying chemical nomenclature, synonyms, or trade names. For instance, a researcher or procurement manager looking for Boc-(R)-3-Amino-4-(2-bromo-phenyl)-butyric acid needs to be certain they are obtaining precisely that compound, and not an isomer or a related substance. In this case, its CAS number, 765263-36-3, provides this essential certainty.
When engaging with chemical suppliers, using the CAS number is the most reliable method to specify a particular chemical. Whether you are looking to buy small quantities for laboratory experiments or bulk orders for manufacturing, quoting the CAS number ensures that both parties are referring to the exact same material. This is particularly crucial for complex molecules like chiral amino acid derivatives, where subtle structural differences can lead to vastly different properties and applications.
The role of the CAS number is not just about identification; it's also about quality assurance and regulatory compliance. Many chemical databases, safety data sheets (SDS), and regulatory documents are indexed by CAS numbers. By referencing the correct CAS number, procurement specialists can more easily access vital information such as purity specifications, safety handling procedures, and supplier verification. This streamlines the purchasing process and minimizes the risk of errors.
For manufacturers and suppliers of fine chemicals, accurately listing CAS numbers for their products is a mark of professionalism and attention to detail. It demonstrates a commitment to clarity and facilitates easier transactions with a global customer base. When you partner with a trusted manufacturer like NINGBO INNO PHARMCHEM CO.,LTD., you can be confident that our product listings, including that of Boc-(R)-3-Amino-4-(2-bromo-phenyl)-butyric acid (CAS 765263-36-3), are meticulously accurate, ensuring you receive the exact chemical you need for your critical applications.
