In the vast universe of chemical compounds, a standardized system for identification is essential for clear communication, accurate record-keeping, and reliable procurement. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves this exact purpose. Each unique chemical substance is assigned a distinct CAS number, acting as a universal identifier that transcends synonyms, trade names, and language barriers. Understanding the significance of CAS numbers is particularly important when sourcing specific fine chemicals, such as (S)-3-Amino-2-(hydroxymethyl)propionic acid, identified by CAS 930784-11-5.

A CAS number is a numerical sequence comprising three parts separated by hyphens, such as the aforementioned 930784-11-5. This seemingly simple sequence provides a direct link to a wealth of information about the specific chemical entity. When researchers or procurement specialists intend to buy or purchase a particular compound, using its CAS number ensures they are obtaining the precise substance they require. This is critical for avoiding confusion and ensuring the integrity of experimental procedures or manufacturing processes.

For specialized intermediates like (S)-3-Amino-2-(hydroxymethyl)propionic acid, the CAS number is instrumental in locating reliable suppliers. Companies like NINGBO INNO PHARMCHEM CO.,LTD. utilize CAS numbers to clearly list their product offerings. This allows customers to efficiently search databases, compare specifications, and confirm the exact chemical they are interested in. The price and availability of a chemical can also be more easily ascertained when referencing its CAS number, facilitating informed purchasing decisions.

Beyond identification, CAS numbers are crucial for regulatory compliance, safety data sheet (SDS) management, and scientific literature searches. They ensure that everyone involved in the handling, use, or trade of chemicals is referring to the same substance. Therefore, familiarizing oneself with the importance of CAS numbers, especially when dealing with specific fine chemicals for advanced applications like peptide synthesis or custom synthesis, is a key competency for professionals in the chemical industry. It streamlines processes, minimizes errors, and ultimately contributes to the efficiency and safety of chemical research and commerce.
