In the complex world of chemistry, precise identification of substances is fundamental. Whether you are a researcher in a lab or a procurement manager sourcing materials, understanding chemical nomenclature and identification systems is crucial. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves as a unique numerical identifier for chemical substances. For intermediates like 4-Formylbenzene-1,3-disulfonic acid disodium salt hydrate, its CAS number – 207291-88-1 – is indispensable.

What is a CAS Number?

A CAS number is a string of numbers separated by hyphens, usually in the format XXX-XX-X, although longer numbers exist. It is assigned by the Chemical Abstracts Service, a division of the American Chemical Society. The CAS Registry is the world's most comprehensive database of chemical substances. Each CAS number is unique and links to a specific chemical compound, whether it's an element, isotope, ion, organic or inorganic compound, polymer, or biological sequence. Its primary purpose is to provide an unambiguous way to identify a chemical substance, regardless of its common name, trade name, or systematic IUPAC name.

Why CAS Numbers are Crucial for Professionals

For R&D scientists and procurement managers, CAS numbers offer several critical advantages:

  • Unambiguous Identification: They eliminate confusion arising from multiple names or synonyms for the same chemical. When you are looking to buy a specific compound like 4-Formylbenzene-1,3-disulfonic acid disodium salt hydrate, using its CAS number (207291-88-1) ensures you are referencing the correct substance.
  • Global Standardization: CAS numbers are recognized and used internationally, facilitating clear communication across borders and within the global chemical industry. This is especially important when dealing with suppliers in different countries, such as purchasing from a manufacturer in China.
  • Database Searching: CAS numbers are the primary key for searching chemical databases, regulatory information, safety data sheets (SDS), and scientific literature.
  • Regulatory Compliance: Government agencies and regulatory bodies worldwide use CAS numbers to track and regulate chemicals.

When engaging with a supplier, always confirm the CAS number to ensure you are receiving the exact material you require. This diligence protects against errors and ensures the integrity of your chemical synthesis or product formulation.
