In the vast and complex world of chemistry, precise identification of chemical substances is fundamental for safety, research, and commerce. The Chemical Abstracts Service (CAS) Registry Number, commonly known as a CAS number, serves as this universal identifier. For professionals in the chemical industry, understanding and utilizing CAS numbers is non-negotiable, especially when sourcing specific compounds like 2-Amino-4-(trifluoromethyl)phenol.

What is a CAS Number?
A CAS number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. It consists of three parts separated by hyphens, with the last digit being a check digit. For example, the CAS number for 2-Amino-4-(trifluoromethyl)phenol is 454-81-9. This number is assigned irrespective of the compound's name, structure, or any other identifying characteristic, ensuring unambiguous identification across different languages and naming conventions.

Why CAS Numbers are Crucial for Buyers and Researchers
The utility of CAS numbers cannot be overstated, particularly when purchasing or researching chemical compounds:

  • Unambiguous Identification: It eliminates confusion arising from multiple synonyms or trade names. When you search for a product to buy, using the CAS number ensures you are looking at the correct substance. For instance, searching for '2-Amino-4-(trifluoromethyl)phenol' might yield similar-sounding but different compounds, but 'CAS 454-81-9' points to one specific chemical.
  • Regulatory Compliance: CAS numbers are used in safety data sheets (SDS), labeling, and regulatory filings worldwide. Accurate identification is essential for compliance with chemical safety and handling regulations.
  • Database Searching: Scientific databases, supplier catalogs, and research literature heavily rely on CAS numbers for efficient searching and retrieval of information. If you're looking for a specific manufacturer or price for 2-Amino-4-(trifluoromethyl)phenol, a CAS number search is often the most effective method.
  • Quality Assurance: When ordering from a chemical supplier, verifying the CAS number against the product specification is a critical step in quality assurance. It confirms that the substance delivered is indeed what was intended.

2-Amino-4-(trifluoromethyl)phenol (CAS 454-81-9) in Practice
As a key fine chemical intermediate, 2-Amino-4-(trifluoromethyl)phenol is used in pharmaceutical synthesis, agrochemicals, and research. Procurement managers and R&D scientists frequently use the CAS number 454-81-9 in their inquiries to suppliers. This precise identifier helps ensure they receive the correct grade and purity of the chemical, directly impacting their synthesis outcomes and project timelines. For example, when requesting a quote from a manufacturer, including 'CAS 454-81-9' in the inquiry guarantees clarity.

In conclusion, CAS numbers are the backbone of chemical communication and commerce. By diligently using and verifying CAS numbers, professionals in the chemical industry can ensure accuracy, safety, and efficiency in their research, development, and procurement processes, making compounds like 2-Amino-4-(trifluoromethyl)phenol readily and accurately accessible.
