In the complex world of chemical procurement and research, precise identification is paramount. The Chemical Abstracts Service (CAS) Registry Number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. Understanding and utilizing CAS numbers, such as for (S)-3-Amino-4-(4-nitrophenyl)butyric Acid HCl (CAS No. 270062-87-8), is fundamental for efficient global sourcing and accurate communication within the scientific community.

What is a CAS Number?

A CAS number is a string of digits, separated by hyphens into three parts (e.g., XXXX-XX-X), that uniquely identifies a specific chemical substance. It is assigned regardless of whether the substance is organic or inorganic, natural or synthetic, or whether it is a simple molecule or a complex polymer. This standardized system eliminates ambiguity and ensures that researchers, manufacturers, and regulatory bodies are all referring to the exact same compound.

The Importance of CAS Numbers in Sourcing:

For procurement managers and researchers looking to buy specific chemicals like (S)-3-Amino-4-(4-nitrophenyl)butyric Acid HCl, the CAS number is the most reliable search parameter. When you search for a chemical by its CAS number, you bypass potential variations in common names, synonyms, or brand names. This is especially useful when dealing with international suppliers, where nomenclature can differ. For example, searching for '270062-87-8' will directly lead you to information about (S)-3-Amino-4-(4-nitrophenyl)butyric Acid HCl, irrespective of whether the supplier lists it under its chemical name, a synonym, or a product code.

Benefits for Buyers and Manufacturers:

  • Accuracy: Ensures you are buying the precise chemical you need, minimizing the risk of errors in synthesis or formulation.
  • Global Reach: Facilitates seamless searching and procurement from chemical suppliers worldwide, including those in China.
  • Regulatory Compliance: CAS numbers are often used in regulatory documentation, safety data sheets (SDS), and inventory management.
  • Efficiency: Speeds up the procurement process by providing a direct and unambiguous identifier.

Utilizing CAS Numbers for (S)-3-Amino-4-(4-nitrophenyl)butyric Acid HCl:

When you are in the market to buy (S)-3-Amino-4-(4-nitrophenyl)butyric Acid HCl, using its CAS number, 270062-87-8, in your search queries will yield the most accurate results. You can then verify the purity (e.g., 97%) and specifications with potential suppliers. This approach ensures you are comparing offers for the exact same product, allowing for informed decisions regarding price and supplier reliability.

In essence, CAS numbers are the universal language of chemistry. By consistently using them, you can navigate the complex landscape of chemical sourcing with greater confidence and efficiency, securing the high-quality intermediates necessary for your research and production.
