In the vast and complex world of chemical compounds, precise identification is not merely a matter of convenience; it is fundamental to safety, research, regulation, and commerce. For 4-Hydroxybenzotriazole, this critical identifier is its CAS Registry Number: 26725-51-9. Understanding the significance of this number is essential for anyone involved in the procurement, research, or handling of this important fine chemical intermediate.

What is a CAS Number?

The CAS number (Chemical Abstracts Service Registry Number) is a unique numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society. Each CAS number is assigned to a single chemical substance. This system provides an unambiguous way to identify a chemical, regardless of its common names, trade names, or synonyms. For 4-Hydroxybenzotriazole, the CAS number 26725-51-9 ensures that everyone, from a scientist in a lab to a procurement manager placing an order, is referring to the exact same compound.

Why is CAS 26725-51-9 So Important for 4-Hydroxybenzotriazole?

The unique nature of the CAS number provides several critical benefits:

• Unambiguous Identification: 4-Hydroxybenzotriazole can have various synonyms (e.g., 1H-1,2,3-Benzotriazol-4-ol, 4-Hydroxy-1H-benzotriazole). Without the CAS number, confusion could easily arise. The number 26725-51-9 eliminates this ambiguity, ensuring you are sourcing the correct chemical.
• Global Standardization: CAS numbers are recognized internationally. When you buy 4-Hydroxybenzotriazole from a supplier anywhere in the world, using the CAS number ensures they understand exactly which product you require. This is vital for international trade and regulatory compliance.
• Database Searching and Information Retrieval: Scientific databases, regulatory listings, and supplier catalogs all use CAS numbers as primary search keys. For R&D scientists, searching for information on 4-Hydroxybenzotriazole (CAS 26725-51-9) yields precise results related to its properties, synthesis, safety, and applications.
• Regulatory Compliance: Government agencies and regulatory bodies rely on CAS numbers for tracking chemicals, managing inventories, and enforcing regulations related to chemical safety and environmental impact.
• Supply Chain Efficiency: For procurement managers, using the CAS number streamlines the ordering process. It reduces the risk of errors in order placement, shipping, and receiving, contributing to a more efficient supply chain.

Ensuring Accuracy When You Buy

When you are looking to purchase 4-Hydroxybenzotriazole, always verify that the CAS number 26725-51-9 is clearly listed on the product documentation, specifications, and order confirmations. A reputable manufacturer and supplier will prominently feature this identifier. If a supplier fails to provide a CAS number or provides an incorrect one, it is a significant red flag regarding their professionalism and the accuracy of their product information.

Conclusion

The CAS number 26725-51-9 is more than just a sequence of digits; it is the definitive key to identifying 4-Hydroxybenzotriazole. For anyone in the chemical industry, from research scientists to procurement professionals, understanding and utilizing CAS numbers is a fundamental practice that ensures accuracy, safety, and efficiency in all chemical-related activities.
