In the vast landscape of chemical compounds, each substance is assigned a unique identifier to ensure clarity, accuracy, and safety in research, trade, and regulation. For 2,6-Dichloropyridine, this identifier is its CAS Registry Number: 2402-78-0. Understanding the significance of CAS numbers, especially for a compound like 2,6-Dichloropyridine, is fundamental for anyone involved in its procurement, research, or application.

What is a CAS Number?

The Chemical Abstracts Service (CAS) Registry is a division of the American Chemical Society. It maintains a comprehensive database of chemical substances, assigning a unique numerical identifier – the CAS Registry Number – to each one. These numbers are designed to be unambiguous and are used globally across scientific literature, regulatory documents, safety data sheets (SDS), and commercial product listings. The CAS number for 2,6-Dichloropyridine, 2402-78-0, serves as its definitive identity.

The Importance of CAS 2402-78-0 for 2,6-Dichloropyridine

For 2,6-Dichloropyridine, the CAS number 2402-78-0 is indispensable for several reasons:

  • Unambiguous Identification: It ensures that researchers, formulators, and procurement specialists are referring to the exact same chemical entity, regardless of regional naming conventions or synonyms. This is crucial for avoiding confusion, especially with isomers of dichloropyridine.
  • Regulatory Compliance: CAS numbers are integral to chemical inventories, safety regulations, and import/export documentation worldwide. Using the correct CAS number ensures compliance with national and international chemical control laws.
  • Information Retrieval: When searching databases, scientific literature, or product catalogs for 2,6-Dichloropyridine, using CAS 2402-78-0 yields precise and relevant results, filtering out information on other related compounds.
  • Safety and Handling: Safety Data Sheets (SDS) are invariably linked to a specific CAS number. This allows users to quickly access critical information on the hazards, safe handling, storage, and emergency procedures for 2,6-Dichloropyridine.
  • Commercial Transactions: For buyers looking to purchase 2,6-Dichloropyridine, the CAS number is a standard part of product specifications on quotations and purchase orders, facilitating clear communication with manufacturers and suppliers.

Sourcing with Confidence: Using CAS 2402-78-0

When you are in the market to buy 2,6-Dichloropyridine, always verify that the product listing or quotation includes CAS 2402-78-0. This simple step can save a great deal of time and prevent costly errors. It signals that the supplier is precise and knowledgeable about the product they are offering.

For those seeking to source 2,6-Dichloropyridine, particularly from manufacturers in China, confirming the CAS number on all documentation is a best practice. This includes requesting quotes, Certificates of Analysis (CoA), and Safety Data Sheets (SDS). A reputable manufacturer will readily provide this information, demonstrating their commitment to product integrity and customer assurance.

Conclusion

The CAS number 2402-78-0 is more than just a sequence of digits; it is the definitive identity of 2,6-Dichloropyridine. It underpins accurate communication, regulatory compliance, and safe handling of this important chemical intermediate. By familiarizing yourself with this identifier and ensuring its presence in your sourcing processes, you can confidently navigate the chemical marketplace and secure the high-quality 2,6-Dichloropyridine needed for your pharmaceutical, agrochemical, or research endeavors.
