In the vast and intricate world of chemistry, precise identification of chemical substances is paramount. This is where Chemical Abstracts Service (CAS) Registry Numbers, commonly known as CAS numbers, play a critical role. These unique numerical identifiers, composed of digits separated by hyphens (e.g., CAS 194805-14-6), ensure that scientists, researchers, and procurement professionals can refer to specific chemical compounds unambiguously. This guide aims to highlight the importance of CAS numbers, using (1R)-5-Bromo-1-methyl-2-trityl-2,3-dihydro-1H-isoindole as an example.

What is a CAS Number and Why is it Important?

A CAS number is a unique identifier assigned to every chemical substance described in the open scientific literature. Unlike names, which can vary by language, synonym, or even common usage, a CAS number is universal and specific. For professionals looking to buy a particular chemical, such as (1R)-5-Bromo-1-methyl-2-trityl-2,3-dihydro-1H-isoindole, searching by its CAS number (194805-14-6) is the most efficient and accurate method. This bypasses any confusion that might arise from different chemical names or synonyms.

CAS Numbers in Sourcing and Research

For R&D scientists and procurement managers, CAS numbers are indispensable tools. When searching for raw materials, they often use queries like 'buy (1R)-5-Bromo-1-methyl-2-trityl-2,3-dihydro-1H-isoindole CAS 194805-14-6,' 'pharmaceutical intermediate CAS number,' or 'OLED chemical 194805-14-6 supplier.' This specificity ensures that they are sourcing the exact compound required, with the correct properties, such as its white powder appearance and 99% purity. A supplier's ability to readily provide and confirm the CAS number builds immediate trust and efficiency in the procurement process.

Ensuring Quality and Consistency with CAS Numbers

While the CAS number identifies the chemical structure, it's crucial to remember that it doesn't inherently specify purity, grade, or physical form. Therefore, when purchasing a chemical by its CAS number, it's vital to partner with reputable manufacturers who provide detailed specifications, including purity levels (e.g., 99% for our (1R)-5-Bromo-1-methyl-2-trityl-2,3-dihydro-1H-isoindole), molecular formula (C28H24BrN), and quality certificates. We, as a leading manufacturer in China, ensure that every batch meets rigorous standards.

The Global Reach of CAS Numbers

The universal nature of CAS numbers facilitates global trade and collaboration in the chemical industry. Whether you are looking to buy from a local supplier or an international manufacturer, using CAS numbers ensures clear communication and accurate transactions. For anyone in need of (1R)-5-Bromo-1-methyl-2-trityl-2,3-dihydro-1H-isoindole, specifying the CAS number 194805-14-6 is the first step to sourcing reliably.

Conclusion

CAS numbers are fundamental to accurate chemical communication and procurement. By utilizing these unique identifiers, professionals can efficiently locate, specify, and source the exact chemical compounds they need for their applications. If you are searching for (1R)-5-Bromo-1-methyl-2-trityl-2,3-dihydro-1H-isoindole or any other chemical, always rely on its CAS number for precise sourcing. We are a trusted supplier ready to provide high-quality chemicals identified by their CAS numbers.
