In the vast and intricate world of chemistry, precise identification of chemical substances is fundamental. This is where CAS Registry Numbers, commonly known as CAS numbers, play an indispensable role. Each unique chemical substance is assigned a distinct CAS number by the Chemical Abstracts Service, a division of the American Chemical Society. These numbers serve as universal identifiers, transcending language and nomenclature variations, making them crucial for accurate sourcing, regulatory compliance, and scientific communication. Let's explore the significance of CAS numbers using N-(2-Pyrazinylcarbonyl)-L-phenylalanine (CAS 114457-94-2) as a case study.

A CAS number, such as 114457-94-2 for N-(2-Pyrazinylcarbonyl)-L-phenylalanine, is typically composed of three parts separated by hyphens. The first part consists of up to seven digits, the second part contains two or more digits, and the third part is a single check digit. This unique numerical sequence ensures that there is no ambiguity when referring to a specific chemical compound. For procurement professionals and researchers, accurately using the CAS number when searching for products like N-(2-Pyrazinylcarbonyl)-L-phenylalanine from manufacturers or suppliers is vital. It guarantees that you are requesting and receiving the exact chemical entity required for your applications, such as Bortezomib synthesis.

The importance of CAS numbers is evident in several key areas within the chemical and pharmaceutical industries. Firstly, in sourcing and purchasing, a CAS number ensures that you are ordering the correct compound. If a supplier lists N-(2-Pyrazinylcarbonyl)-L-phenylalanine with its CAS number 114457-94-2, there is a high degree of certainty about the substance's identity. This eliminates potential confusion arising from different trade names or systematic nomenclature variations.

Secondly, CAS numbers are critical for regulatory compliance and safety data. Material Safety Data Sheets (MSDS) and Safety Data Sheets (SDS) universally reference CAS numbers, providing essential information on hazards, handling, storage, and emergency procedures. When a manufacturer supplies N-(2-Pyrazinylcarbonyl)-L-phenylalanine, its accompanying documentation will invariably include the CAS number 114457-94-2.

Thirdly, in research and development, CAS numbers facilitate efficient literature searches and data retrieval. Whether you are looking for synthesis routes, property data, or application examples for N-(2-Pyrazinylcarbonyl)-L-phenylalanine, using its CAS number in databases like Chemical Abstracts Service or scientific search engines is the most effective way to find relevant information. This accuracy is indispensable for researchers working on projects that require specific intermediates.

In conclusion, CAS numbers are more than just identifiers; they are foundational tools for precision, safety, and efficiency in the chemical industry. For anyone looking to buy N-(2-Pyrazinylcarbonyl)-L-phenylalanine or any other chemical, always verify and use its correct CAS number. Working with manufacturers like Ningbo Inno Pharmchem Co., Ltd. who prioritize accurate chemical identification ensures you receive exactly what you need for your critical processes.
